For Visual Basic, check that this parameter is passed by reference + ("as any"), not by value ("as long"). + + 5. deflate() or inflate() returns Z_BUF_ERROR. + + Before making the call, make sure that avail_in and avail_out are not + zero. When setting the parameter flush equal to Z_FINISH, also make sure + that avail_out is big enough to allow processing all pending input. + Note that a Z_BUF_ERROR is not fatal--another call to deflate() or + inflate() can be made with more input or output space. A Z_BUF_ERROR + may in fact be unavoidable depending on how the functions are used, since + it is not possible to tell whether or not there is more output pending + when strm.avail_out returns with zero. + + 6. Where's the zlib documentation (man pages, etc.)? + + It's in zlib.h for the moment, and Francis S. Lin has converted it to a + web page zlib.html. Volunteers to transform this to Unix-style man pages, + please contact us (zlib@gzip.org). Examples of zlib usage are in the files + example.c and minigzip.c. + + 7. Why don't you use GNU autoconf or libtool or ...? + + Because we would like to keep zlib as a very small and simple + package. zlib is rather portable and doesn't need much configuration. + + 8. I found a bug in zlib. + + Most of the time, such problems are due to an incorrect usage of + zlib. Please try to reproduce the problem with a small program and send + the corresponding source to us at zlib@gzip.org . Do not send + multi-megabyte data files without prior agreement. + + 9. Why do I get "undefined reference to gzputc"? + + If "make test" produces something like + + example.o(.text+0x154): undefined reference to `gzputc' + + check that you don't have old files libz.* in /usr/lib, /usr/local/lib or + /usr/X11R6/lib. Remove any old versions, then do "make install". + +10. I need a Delphi interface to zlib. + + See the contrib/delphi directory in the zlib distribution. + +11. Can zlib handle .zip archives? + + Not by itself, no. See the directory contrib/minizip in the zlib + distribution. + +12. Can zlib handle .Z files? + + No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt + the code of uncompress on your own. + +13. How can I make a Unix shared library? + + make clean + ./configure -s + make + +14. How do I install a shared zlib library on Unix? + + After the above, then: + + make install + + However, many flavors of Unix come with a shared zlib already installed. + Before going to the trouble of compiling a shared version of zlib and + trying to install it, you may want to check if it's already there! If you + can #include <zlib.h>, it's there. The -lz option will probably link to it. + +15. I have a question about OttoPDF. + + We are not the authors of OttoPDF. The real author is on the OttoPDF web + site: Joel Hainley, jhainley@myndkryme.com. + +16. Can zlib decode Flate data in an Adobe PDF file? + + Yes. See http://www.fastio.com/ (ClibPDF), or http://www.pdflib.com/ . + To modify PDF forms, see http://sourceforge.net/projects/acroformtool/ . + +17. Why am I getting this "register_frame_info not found" error on Solaris? + + After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib + generates an error such as: + + ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so: + symbol __register_frame_info: referenced symbol not found + + The symbol __register_frame_info is not part of zlib, it is generated by + the C compiler (cc or gcc). You must recompile applications using zlib + which have this problem. This problem is specific to Solaris. See + http://www.sunfreeware.com for Solaris versions of zlib and applications + using zlib. + +18. Why does gzip give an error on a file I make with compress/deflate? + + The compress and deflate functions produce data in the zlib format, which + is different and incompatible with the gzip format. The gz* functions in + zlib on the other hand use the gzip format. Both the zlib and gzip + formats use the same compressed data format internally, but have different + headers and trailers around the compressed data. + +19. Ok, so why are there two different formats? + + The gzip format was designed to retain the directory information about + a single file, such as the name and last modification date. The zlib + format on the other hand was designed for in-memory and communication + channel applications, and has a much more compact header and trailer and + uses a faster integrity check than gzip. + +20. Well that's nice, but how do I make a gzip file in memory? + + You can request that deflate write the gzip format instead of the zlib + format using deflateInit2(). You can also request that inflate decode + the gzip format using inflateInit2(). Read zlib.h for more details. + +21. Is zlib thread-safe? + + Yes. However any library routines that zlib uses and any application- + provided memory allocation routines must also be thread-safe. zlib's gz* + functions use stdio library routines, and most of zlib's functions use the + library memory allocation routines by default. zlib's Init functions allow + for the application to provide custom memory allocation routines. + + Of course, you should only operate on any given zlib or gzip stream from a + single thread at a time. + +22. Can I use zlib in my commercial application? + + Yes. Please read the license in zlib.h. + +23. Is zlib under the GNU license? + + No. Please read the license in zlib.h. + +24. The license says that altered source versions must be "plainly marked". So + what exactly do I need to do to meet that requirement? + + You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In + particular, the final version number needs to be changed to "f", and an + identification string should be appended to ZLIB_VERSION. Version numbers + x.x.x.f are reserved for modifications to zlib by others than the zlib + maintainers. For example, if the version of the base zlib you are altering + is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and + ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also + update the version strings in deflate.c and inftrees.c. + + For altered source distributions, you should also note the origin and + nature of the changes in zlib.h, as well as in ChangeLog and README, along + with the dates of the alterations. The origin should include at least your + name (or your company's name), and an email address to contact for help or + issues with the library. + + Note that distributing a compiled zlib library along with zlib.h and + zconf.h is also a source distribution, and so you should change + ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes + in zlib.h as you would for a full source distribution. + +25. Will zlib work on a big-endian or little-endian architecture, and can I + exchange compressed data between them? + + Yes and yes. + +26. Will zlib work on a 64-bit machine? + + It should. It has been tested on 64-bit machines, and has no dependence + on any data types being limited to 32-bits in length. If you have any + difficulties, please provide a complete problem report to zlib@gzip.org + +27. Will zlib decompress data from the PKWare Data Compression Library? + + No. The PKWare DCL uses a completely different compressed data format + than does PKZIP and zlib. However, you can look in zlib's contrib/blast + directory for a possible solution to your problem. + +28. Can I access data randomly in a compressed stream? + + No, not without some preparation. If when compressing you periodically + use Z_FULL_FLUSH, carefully write all the pending data at those points, + and keep an index of those locations, then you can start decompression + at those points. You have to be careful to not use Z_FULL_FLUSH too + often, since it can significantly degrade compression. + +29. Does zlib work on MVS, OS/390, CICS, etc.? + + We don't know for sure. We have heard occasional reports of success on + these systems. If you do use it on one of these, please provide us with + a report, instructions, and patches that we can reference when we get + these questions. Thanks. + +30. Is there some simpler, easier to read version of inflate I can look at + to understand the deflate format? + + First off, you should read RFC 1951. Second, yes. Look in zlib's + contrib/puff directory. + +31. Does zlib infringe on any patents? + + As far as we know, no. In fact, that was originally the whole point behind + zlib. Look here for some more information: + + http://www.gzip.org/#faq11 + +32. Can zlib work with greater than 4 GB of data? + + Yes. inflate() and deflate() will process any amount of data correctly. + Each call of inflate() or deflate() is limited to input and output chunks + of the maximum value that can be stored in the compiler's "unsigned int" + type, but there is no limit to the number of chunks. Note however that the + strm.total_in and strm_total_out counters may be limited to 4 GB. These + counters are provided as a convenience and are not used internally by + inflate() or deflate(). The application can easily set up its own counters + updated after each call of inflate() or deflate() to count beyond 4 GB. + compress() and uncompress() may be limited to 4 GB, since they operate in a + single call. gzseek() and gztell() may be limited to 4 GB depending on how + zlib is compiled. See the zlibCompileFlags() function in zlib.h. + + The word "may" appears several times above since there is a 4 GB limit + only if the compiler's "long" type is 32 bits. If the compiler's "long" + type is 64 bits, then the limit is 16 exabytes. + +33. Does zlib have any security vulnerabilities? + + The only one that we are aware of is potentially in gzprintf(). If zlib + is compiled to use sprintf() or vsprintf(), then there is no protection + against a buffer overflow of a 4K string space, other than the caller of + gzprintf() assuring that the output will not exceed 4K. On the other + hand, if zlib is compiled to use snprintf() or vsnprintf(), which should + normally be the case, then there is no vulnerability. The ./configure + script will display warnings if an insecure variation of sprintf() will + be used by gzprintf(). Also the zlibCompileFlags() function will return + information on what variant of sprintf() is used by gzprintf(). + + If you don't have snprintf() or vsnprintf() and would like one, you can + find a portable implementation here: + + http://www.ijs.si/software/snprintf/ + + Note that you should be using the most recent version of zlib. Versions + 1.1.3 and before were subject to a double-free vulnerability. + +34. Is there a Java version of zlib? + + Probably what you want is to use zlib in Java. zlib is already included + as part of the Java SDK in the java.util.zip package. If you really want + a version of zlib written in the Java language, look on the zlib home + page for links: http://www.zlib.org/ + +35. I get this or that compiler or source-code scanner warning when I crank it + up to maximally-pedantic. Can't you guys write proper code? + + Many years ago, we gave up attempting to avoid warnings on every compiler + in the universe. It just got to be a waste of time, and some compilers + were downright silly. So now, we simply make sure that the code always + works. + +36. Valgrind (or some similar memory access checker) says that deflate is + performing a conditional jump that depends on an uninitialized value. + Isn't that a bug? + + No. That is intentional for performance reasons, and the output of + deflate is not affected. This only started showing up recently since + zlib 1.2.x uses malloc() by default for allocations, whereas earlier + versions used calloc(), which zeros out the allocated memory. + +37. Will zlib read the (insert any ancient or arcane format here) compressed + data format? + + Probably not. Look in the comp.compression FAQ for pointers to various + formats and associated software. + +38. How can I encrypt/decrypt zip files with zlib? + + zlib doesn't support encryption. The original PKZIP encryption is very weak + and can be broken with freely available programs. To get strong encryption, + use GnuPG, http://www.gnupg.org/ , which already includes zlib compression. + For PKZIP compatible "encryption", look at http://www.info-zip.org/ + +39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings? + + "gzip" is the gzip format, and "deflate" is the zlib format. They should + probably have called the second one "zlib" instead to avoid confusion + with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616 + correctly points to the zlib specification in RFC 1950 for the "deflate" + transfer encoding, there have been reports of servers and browsers that + incorrectly produce or expect raw deflate data per the deflate + specficiation in RFC 1951, most notably Microsoft. So even though the + "deflate" transfer encoding using the zlib format would be the more + efficient approach (and in fact exactly what the zlib format was designed + for), using the "gzip" transfer encoding is probably more reliable due to + an unfortunate choice of name on the part of the HTTP 1.1 authors. + + Bottom line: use the gzip format for HTTP 1.1 encoding. + +40. Does zlib support the new "Deflate64" format introduced by PKWare? + + No. PKWare has apparently decided to keep that format proprietary, since + they have not documented it as they have previous compression formats. + In any case, the compression improvements are so modest compared to other + more modern approaches, that it's not worth the effort to implement. + +41. Can you please sign these lengthy legal documents and fax them back to us + so that we can use your software in our product? + + No. Go away.

Compression algorithm (deflate) + +The deflation algorithm used by gzip (also zip and zlib) is a variation of +LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in +the input data. The second occurrence of a string is replaced by a +pointer to the previous string, in the form of a pair (distance, +length). Distances are limited to 32K bytes, and lengths are limited +to 258 bytes. When a string does not occur anywhere in the previous +32K bytes, it is emitted as a sequence of literal bytes. (In this +description, `string' must be taken as an arbitrary sequence of bytes, +and is not restricted to printable characters.) + +Literals or match lengths are compressed with one Huffman tree, and +match distances are compressed with another tree. The trees are stored +in a compact form at the start of each block. The blocks can have any +size (except that the compressed data for one block must fit in +available memory). A block is terminated when deflate() determines that +it would be useful to start another block with fresh trees. (This is +somewhat similar to the behavior of LZW-based _compress_.) + +Duplicated strings are found using a hash table. All input strings of +length 3 are inserted in the hash table. A hash index is computed for +the next 3 bytes. If the hash chain for this index is not empty, all +strings in the chain are compared with the current input string, and +the longest match is selected. + +The hash chains are searched starting with the most recent strings, to +favor small distances and thus take advantage of the Huffman encoding. +The hash chains are singly linked. There are no deletions from the +hash chains, the algorithm simply discards matches that are too old. + +To avoid a worst-case situation, very long hash chains are arbitrarily +truncated at a certain length, determined by a runtime option (level +parameter of deflateInit). So deflate() does not always find the longest +possible match but generally finds a match which is long enough. + +deflate() also defers the selection of matches with a lazy evaluation +mechanism. After a match of length N has been found, deflate() searches for +a longer match at the next input byte. If a longer match is found, the +previous match is truncated to a length of one (thus producing a single +literal byte) and the process of lazy evaluation begins again. Otherwise, +the original match is kept, and the next match search is attempted only N +steps later. + +The lazy match evaluation is also subject to a runtime parameter. If +the current match is long enough, deflate() reduces the search for a longer +match, thus speeding up the whole process. If compression ratio is more +important than speed, deflate() attempts a complete second search even if +the first match is already long enough. + +The lazy match evaluation is not performed for the fastest compression +modes (level parameter 1 to 3). For these fast modes, new strings +are inserted in the hash table only when no match was found, or +when the match is not too long. This degrades the compression ratio +but saves time since there are both fewer insertions and fewer searches. + + +2. Decompression algorithm (inflate) + +2.1 Introduction + +The key question is how to represent a Huffman code (or any prefix code) so +that you can decode fast. The most important characteristic is that shorter +codes are much more common than longer codes, so pay attention to decoding the +short codes fast, and let the long codes take longer to decode. + +inflate() sets up a first level table that covers some number of bits of +input less than the length of longest code. It gets that many bits from the +stream, and looks it up in the table. The table will tell if the next +code is that many bits or less and how many, and if it is, it will tell +the value, else it will point to the next level table for which inflate() +grabs more bits and tries to decode a longer code. + +How many bits to make the first lookup is a tradeoff between the time it +takes to decode and the time it takes to build the table. If building the +table took no time (and if you had infinite memory), then there would only +be a first level table to cover all the way to the longest code. However, +building the table ends up taking a lot longer for more bits since short +codes are replicated many times in such a table. What inflate() does is +simply to make the number of bits in the first table a variable, and then +to set that variable for the maximum speed. + +For inflate, which has 286 possible codes for the literal/length tree, the size +of the first table is nine bits. Also the distance trees have 30 possible +values, and the size of the first table is six bits. Note that for each of +those cases, the table ended up one bit longer than the ``average'' code +length, i.e. the code length of an approximately flat code which would be a +little more than eight bits for 286 symbols and a little less than five bits +for 30 symbols. + + +2.2 More details on the inflate table lookup + +Ok, you want to know what this cleverly obfuscated inflate tree actually +looks like. You are correct that it's not a Huffman tree. It is simply a +lookup table for the first, let's say, nine bits of a Huffman symbol. The +symbol could be as short as one bit or as long as 15 bits. If a particular +symbol is shorter than nine bits, then that symbol's translation is duplicated +in all those entries that start with that symbol's bits. For example, if the +symbol is four bits, then it's duplicated 32 times in a nine-bit table. If a +symbol is nine bits long, it appears in the table once. + +If the symbol is longer than nine bits, then that entry in the table points +to another similar table for the remaining bits. Again, there are duplicated +entries as needed. The idea is that most of the time the symbol will be short +and there will only be one table look up. (That's whole idea behind data +compression in the first place.) For the less frequent long symbols, there +will be two lookups. If you had a compression method with really long +symbols, you could have as many levels of lookups as is efficient. For +inflate, two is enough. + +So a table entry either points to another table (in which case nine bits in +the above example are gobbled), or it contains the translation for the symbol +and the number of bits to gobble. Then you start again with the next +ungobbled bit. + +You may wonder: why not just have one lookup table for how ever many bits the +longest symbol is? The reason is that if you do that, you end up spending +more time filling in duplicate symbol entries than you do actually decoding. +At least for deflate's output that generates new trees every several 10's of +kbytes. You can imagine that filling in a 2^15 entry table for a 15-bit code +would take too long if you're only decoding several thousand symbols. At the +other extreme, you could make a new table for every bit in the code. In fact, +that's essentially a Huffman tree. But then you spend two much time +traversing the tree while decoding, even for short symbols. + +So the number of bits for the first lookup table is a trade of the time to +fill out the table vs. the time spent looking at the second level and above of +the table. + +Here is an example, scaled down: + +The code being decoded, with 10 symbols, from 1 to 6 bits long: + +A: 0 +B: 10 +C: 1100 +D: 11010 +E: 11011 +F: 11100 +G: 11101 +H: 11110 +I: 111110 +J: 111111 + +Let's make the first table three bits long (eight entries): + +000: A,1 +001: A,1 +010: A,1 +011: A,1 +100: B,2 +101: B,2 +110: -> table X (gobble 3 bits) +111: -> table Y (gobble 3 bits) + +Each entry is what the bits decode as and how many bits that is, i.e. how +many bits to gobble. Or the entry points to another table, with the number of +bits to gobble implicit in the size of the table. + +Table X is two bits long since the longest code starting with 110 is five bits +long: + +00: C,1 +01: C,1 +10: D,2 +11: E,2 + +Table Y is three bits long since the longest code starting with 111 is six +bits long: + +000: F,2 +001: F,2 +010: G,2 +011: G,2 +100: H,2 +101: H,2 +110: I,3 +111: J,3 + +So what we have here are three tables with a total of 20 entries that had to +be constructed. That's compared to 64 entries for a single table. Or +compared to 16 entries for a Huffman tree (six two entry tables and one four +entry table). Assuming that the code ideally represents the probability of +the symbols, it takes on the average 1.25 lookups per symbol. That's compared +to one lookup for the single table, or 1.66 lookups per symbol for the +Huffman tree. + +There, I think that gives you a picture of what's going on. For inflate, the +meaning of a particular symbol is often more than just a letter. It can be a +byte (a "literal"), or it can be either a length or a distance which +indicates a base value and a number of bits to fetch after the code that is +added to the base value. Or it might be the special end-of-block code.

There are a series of bugs +and security problems associated with that old zlib version, and +we recommend the users to update their ZLib unit. + + +Summary of modifications +======================== + +- Improved makefile, adapted to zlib version 1.2.1. + +- Some field types from TZStreamRec are changed from Integer to + Longint, for consistency with the zlib.h header, and for 64-bit + readiness. + +- The zlib_version constant is updated. + +- The new Z_RLE strategy has its corresponding symbolic constant. + +- The allocation and deallocation functions and function types + (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl, + and _malloc and _free are added as C RTL stubs. As a result, + the original C sources of zlib can be compiled out of the box, + and linked to the ZLib unit. + + +Suggestions for improvements +============================ + +Currently, the ZLib unit provides only a limited wrapper around +the zlib library, and much of the original zlib functionality is +missing. Handling compressed file formats like ZIP/GZIP or PNG +cannot be implemented without having this functionality. +Applications that handle these formats are either using their own, +duplicated code, or not using the ZLib unit at all. + +Here are a few suggestions: + +- Checksum class wrappers around adler32() and crc32(), similar + to the Java classes that implement the java.util.zip.Checksum + interface. + +- The ability to read and write raw deflate streams, without the + zlib stream header and trailer. Raw deflate streams are used + in the ZIP file format. + +- The ability to read and write gzip streams, used in the GZIP + file format, and normally produced by the gzip program. + +- The ability to select a different compression strategy, useful + to PNG and MNG image compression, and to multimedia compression + in general.

+The wrapper includes support for inflating/deflating memory buffers,
+.Net streaming wrappers for the gz streams part of zlib, and wrappers
+for the checksum parts of zlib. See DotZLib/UnitTests.cs for examples.
+
+Directory structure:
+--------------------
+
+LICENSE_1_0.txt - License file.
+readme.txt - This file.
+DotZLib.chm - Class library documentation
+DotZLib.build - NAnt build file
+DotZLib.sln - Microsoft Visual Studio 2003 solution file
+
+DotZLib\*.cs - Source files for the class library
+
+Unit tests:
+-----------
+The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher.
+To include unit tests in the build, define nunit before building.
+
+
+Build instructions:
+-------------------
+
+1. Using Visual Studio.Net 2003:
+ Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll)
+ will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on
+ you are building the release or debug version of the library. Check
+ DotZLib/UnitTests.cs for instructions on how to include unit tests in the
+ build.
+
+2. Using NAnt:
+ Open a command prompt with access to the build environment and run nant
+ in the same directory as the DotZLib.build file.
+ You can define 2 properties on the nant command-line to control the build:
+ debug={true|false} to toggle between release/debug builds (default=true).
+ nunit={true|false} to include or esclude unit tests (default=true).
+ Also the target clean will remove binaries.
+ Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release
+ or ./DotZLib/bin/debug, depending on whether you are building the release
+ or debug version of the library.
+
+ Examples:
+ nant -D:debug=false -D:nunit=false
+ will build a release mode version of the library without unit tests.
+ nant
+ will build a debug version of the library with unit tests
+ nant clean
+ will remove all previously built files.

<christop@charm.net> + * Please use the copyright conditions above. + * + * This version (Jan-23-2003) of inflate_fast was coded and tested under + * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that + * machine, I found that gzip style archives decompressed about 20% faster than + * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will + * depend on how large of a buffer is used for z_stream.next_in & next_out + * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in + * stream processing I/O and crc32/addler32. In my case, this routine used + * 70% of the cpu time and crc32 used 20%. + * + * I am confident that this version will work in the general case, but I have + * not tested a wide variety of datasets or a wide variety of platforms. + * + * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating. + * It should be a runtime flag instead of compile time flag... + * + * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction. + * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code + * is compiled. Without either option, runtime detection is enabled. Runtime + * detection should work on all modern cpus and the recomended algorithm (flip + * ID bit on eflags and then use the cpuid instruction) is used in many + * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12 + * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o + * inffast.obj generates a COFF object which can then be linked with MSVC++ + * compiled code. Tested under FreeBSD 4.7 with gcc-2.95. + * + * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and + * slower than compiler generated code). Adjusted cpuid check to use the MMX + * code only for Pentiums < P4 until I have more data on the P4. Speed + * improvment is only about 15% on the Athlon when compared with code generated + * with MSVC++. Not sure yet, but I think the P4 will also be slower using the + * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and + * have less latency than MMX ops. Added code to buffer the last 11 bytes of + * the input stream since the MMX code grabs bits in chunks of 32, which + * differs from the inffast.c algorithm. I don't think there would have been + * read overruns where a page boundary was crossed (a segfault), but there + * could have been overruns when next_in ends on unaligned memory (unintialized + * memory read). + * + * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C + * version of the non-MMX code so that it doesn't depend on zstrm and zstate + * structure offsets which are hard coded in this file. This was last tested + * with zlib-1.2.0 which is currently in beta testing, newer versions of this + * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and + * http://www.charm.net/~christop/zlib/ + */ + + +/* + * if you have underscore linking problems (_inflate_fast undefined), try + * using -DGAS_COFF + */ +#if ! defined( GAS_COFF ) && ! defined( GAS_ELF ) + +#if defined( WIN32 ) || defined( __CYGWIN__ ) +#define GAS_COFF /* windows object format */ +#else +#define GAS_ELF +#endif + +#endif /* !

+/*
+ Decode literal, length, and distance codes and write out the resulting
+ literal and match bytes until either not enough input or output is
+ available, an end-of-block is encountered, or a data error is encountered.
+ When large enough input and output buffers are supplied to inflate(), for
+ example, a 16K input buffer and a 64K output buffer, more than 95% of the
+ inflate execution time is spent in this routine.
+
+ Entry assumptions:
+
+ state->mode == LEN
+ strm->avail_in >= 6
+ strm->avail_out >= 258
+ start >= strm->avail_out
+ state->bits < 8
+
+ On return, state->mode is one of:
+
+ LEN -- ran out of enough output space or enough available input
+ TYPE -- reached end of block code, inflate() to interpret next block
+ BAD -- error in block data
+
+ Notes:
+
+ - The maximum input bits used by a length/distance pair is 15 bits for the
+ length code, 5 bits for the length extra, 15 bits for the distance code,
+ and 13 bits for the distance extra. This totals 48 bits, or six bytes.
+ Therefore if strm->avail_in >= 6, then there is enough input to avoid
+ checking for available input while decoding.
+
+ - The maximum bytes that a single length/distance pair can output is 258
+ bytes, which is the maximum length that can be coded. inflate_fast()
+ requires strm->avail_out >= 258 for each loop to avoid checking for
+ output space.

+; this file contain two implementation of longest_match
+;
+; longest_match_7fff : written 1996 by Gilles Vollant optimized for
+; first Pentium. Assume s->w_mask == 0x7fff
+; longest_match_686 : written by Brian raiter (1998), optimized for Pentium Pro
+;
+; for using an seembly version of longest_match, you need define ASMV in project
+; There is two way in using gvmat32.asm
+;
+; A) Suggested method
+; if you want include both longest_match_7fff and longest_match_686
+; compile the asm file running
+; ml /coff /Zi /Flgvmat32.lst /c gvmat32.asm
+; and include gvmat32c.c in your project
+; if you have an old cpu (386,486 or first Pentium) and s->w_mask==0x7fff,
+; longest_match_7fff will be used
+; if you have a more modern CPU (Pentium Pro, II and higher)
+; longest_match_686 will be used
+; on old cpu with s->w_mask!=0x7fff, longest_match_686 will be used,
+; but this is not a sitation you'll find often
+;
+; B) Alternative
+; if you are not interresed in old cpu performance and want the smaller
+; binaries possible
+;
+; compile the asm file running
+; ml /coff /Zi /c /Flgvmat32.lst /DNOOLDPENTIUMCODE gvmat32.asm
+; and do not include gvmat32c.c in your project (ou define also
+; NOOLDPENTIUMCODE)
+;
+; note : as I known, longest_match_686 is very faster than longest_match_7fff
+; on pentium Pro/II/III, faster (but less) in P4, but it seem
+; longest_match_7fff can be faster (very very litte) on AMD Athlon64/K8

In particular, + there is no conversion of unsigned int into a Pascal unsigned + integer. The Word type is non-portable and has the same size + (16 bits) both in a 16-bit and in a 32-bit environment, unlike + Integer. Even if there is a 32-bit Cardinal type, there is no + real need for unsigned int in zlib under a 32-bit environment. + +- Except for the callbacks, the zlib function interfaces are + assuming the calling convention normally used in Pascal + (__pascal for DOS and Windows16, __fastcall for Windows32). + Since the cdecl keyword is used, the old Turbo Pascal does + not work with this interface. + +- The gz* function interfaces are not translated, to avoid + interfacing problems with the C runtime library.

It +does so more slowly than zlib, but the code is about one-fifth the size of the +inflate code in zlib, and written to be very easy to read. + +Why I wrote this -- + +puff.c was written to document the deflate format unambiguously, by virtue of +being working C code. It is meant to supplement RFC 1951, which formally +describes the deflate format. I have received many questions on details of the +deflate format, and I hope that reading this code will answer those questions. +puff.c is heavily commented with details of the deflate format, especially +those little nooks and cranies of the format that might not be obvious from a +specification. + +puff.c may also be useful in applications where code size or memory usage is a +very limited resource, and speed is not as important. + +How to use it -- + +Well, most likely you should just be reading puff.c and using zlib for actual +applications, but if you must ... + +Include puff.h in your code, which provides this prototype: + +int puff(unsigned char *dest, /* pointer to destination pointer */ + unsigned long *destlen, /* amount of output space */ + unsigned char *source, /* pointer to source data pointer */ + unsigned long *sourcelen); /* amount of input available */ + +Then you can call puff() to decompress a deflate stream that is in memory in +its entirety at source, to a sufficiently sized block of memory for the +decompressed data at dest. puff() is the only external symbol in puff.c The +only C library functions that puff.c needs are setjmp() and longjmp(), which +are used to simplify error checking in the code to improve readabilty. puff.c +does no memory allocation, and uses less than 2K bytes off of the stack. + +If destlen is not enough space for the uncompressed data, then inflate will +return an error without writing more than destlen bytes. Note that this means +that in order to decompress the deflate data successfully, you need to know +the size of the uncompressed data ahead of time. + +If needed, puff() can determine the size of the uncompressed data with no +output space. This is done by passing dest equal to (unsigned char *)0. Then +the initial value of *destlen is ignored and *destlen is set to the length of +the uncompressed data. So if the size of the uncompressed data is not known, +then two passes of puff() can be used--first to determine the size, and second +to do the actual inflation after allocating the appropriate memory. Not +pretty, but it works. (This is one of the reasons you should be using zlib.) + +The deflate format is self-terminating. If the deflate stream does not end +in *sourcelen bytes, puff() will return an error without reading at or past +endsource. + +On return, *sourcelen is updated to the amount of input data consumed, and +*destlen is updated to the size of the uncompressed data.

So incomplete distance codes of one symbol + * should be permitted, and the receipt of invalid codes should be handled. + * + * - It is also possible to have a single literal/length code, but that code + * must be the end-of-block code, since every dynamic block has one. This + * is not the most efficient way to create an empty block (an empty fixed + * block is fewer bits), but it is allowed by the format. So incomplete + * literal/length codes of one symbol should also be permitted. + * + * - If there are only literal codes and no lengths, then there are no distance + * codes. This is represented by one distance code with zero bits. + * + * - The list of up to 286 length/literal lengths and up to 30 distance lengths + * are themselves compressed using Huffman codes and run-length encoding. In + * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means + * that length, and the symbols 16, 17, and 18 are run-length instructions. + * Each of 16, 17, and 18 are follwed by extra bits to define the length of + * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10 + * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols + * are common, hence the special coding for zero lengths. + * + * - The symbols for 0..18 are Huffman coded, and so that code must be + * described first. This is simply a sequence of up to 19 three-bit values + * representing no code (0) or the code length for that symbol (1..7). + * + * - A dynamic block starts with three fixed-size counts from which is computed + * the number of literal/length code lengths, the number of distance code + * lengths, and the number of code length code lengths (ok, you come up with + * a better name!) in the code descriptions. For the literal/length and + * distance codes, lengths after those provided are considered zero, i.e. no + * code. The code length code lengths are received in a permuted order (see + * the order[] array below) to make a short code length code length list more + * likely. As it turns out, very short and very long codes are less likely + * to be seen in a dynamic code description, hence what may appear initially + * to be a peculiar ordering. + * + * - Given the number of literal/length code lengths (nlen) and distance code + * lengths (ndist), then they are treated as one long list of nlen + ndist + * code lengths. Therefore run-length coding can and often does cross the + * boundary between the two sets of lengths. + * + * - So to summarize, the code description at the start of a dynamic block is + * three counts for the number of code lengths for the literal/length codes, + * the distance codes, and the code length codes. This is followed by the + * code length code lengths, three bits each. This is used to construct the + * code length code which is used to read the remainder of the lengths. Then + * the literal/length code lengths and distance lengths are read as a single + * set of lengths using the code length codes. Codes are constructed from + * the resulting two sets of lengths, and then finally you can start + * decoding actual compressed data in the block. + * + * - For reference, a "typical" size for the code description in a dynamic + * block is around 80 bytes. + */ +local int dynamic(struct state *s) +{ + int nlen, ndist, ncode; /* number of lengths in descriptor */ + int index; /* index of lengths[] */ + int err; /* construct() return value */ + short lengths[MAXCODES]; /* descriptor code lengths */ + short lencnt[MAXBITS+1], lensym[MAXLCODES]; /* lencode memory */ + short distcnt[MAXBITS+1], distsym[MAXDCODES]; /* distcode memory */ + struct huffman lencode = {lencnt, lensym}; /* length code */ + struct huffman distcode = {distcnt, distsym}; /* distance code */ + static const short order[19] = /* permutation of code length codes */ + {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; + + /* get number of lengths in each table, check lengths */ + nlen = bits(s, 5) + 257; + ndist = bits(s, 5) + 1; + ncode = bits(s, 4) + 4; + if (nlen > MAXLCODES || ndist > MAXDCODES) + return -3; /* bad counts */ + + /* read code length code lengths (really), missing lengths are zero */ + for (index = 0; index < ncode; index++) + lengths[order[index]] = bits(s, 3); + for (; index < 19; index++) + lengths[order[index]] = 0; + + /* build huffman table for code lengths codes (use lencode temporarily) */ + err = construct(&lencode, lengths, 19); + if (err != 0) return -4; /* require complete code set here */ + + /* read length/literal and distance code length tables */ + index = 0; + while (index < nlen + ndist) { + int symbol; /* decoded value */ + int len; /* last length to repeat */ + + symbol = decode(s, &lencode); + if (symbol < 16) /* length in 0..15 */ + lengths[index++] = symbol; + else { /* repeat instruction */ + len = 0; /* assume repeating zeros */ + if (symbol == 16) { /* repeat last length 3..6 times */ + if (index == 0) return -5; /* no last length! */ + len = lengths[index - 1]; /* last length */ + symbol = 3 + bits(s, 2); + } + else if (symbol == 17) /* repeat zero 3..10 times */ + symbol = 3 + bits(s, 3); + else /* == 18, repeat zero 11..138 times */ + symbol = 11 + bits(s, 7); + if (index + symbol > nlen + ndist) + return -6; /* too many lengths! */ + while (symbol--) /* repeat last or zero symbol times */ + lengths[index++] = len; + } + } + + /* build huffman table for literal/length codes */ + err = construct(&lencode, lengths, nlen); + if (err < 0 || (err > 0 && nlen - lencode.count[0] != 1)) + return -7; /* only allow incomplete codes if just one code */ + + /* build huffman table for distance codes */ + err = construct(&distcode, lengths + nlen, ndist); + if (err < 0 || (err > 0 && ndist - distcode.count[0] != 1)) + return -8; /* only allow incomplete codes if just one code */ + + /* decode data until end-of-block code */ + return codes(s, &lencode, &distcode); +} + +/* + * Inflate source to dest.

+========================================================
+
+This directory contains projects that build zlib and minizip using
+Microsoft Visual C++ 7.0/7.1, and Visual C++ .
+
+You don't need to build these projects yourself. You can download the
+binaries from:
+ http://www.winimage.com/zLibDll
+
+More information can be found at this site.
+
+
+Build instructions for Visual Studio 7.x (32 bits)
+--------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- Download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc7.
+- Open contrib\vstudio\vc7\zlibvc.sln with Microsoft Visual C++ 7.x
+ (Visual Studio .Net 2002 or 2003).
+
+Build instructions for Visual Studio 2005 (32 bits or 64 bits)
+--------------------------------------------------------------
+- Uncompress current zlib, including all contrib/* files
+- For 32 bits only: download the crtdll library from
+ http://www.winimage.com/zLibDll/crtdll.zip
+ Unzip crtdll.zip to extract crtdll.lib on contrib\vstudio\vc8.
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+Build instructions for Visual Studio 2005 64 bits, PSDK compiler
+----------------------------------------------------------------
+at the time of writing this text file, Visual Studio 2005 (and
+ Microsoft Visual C++ 8.0) is on the beta 2 stage.
+Using you can get the free 64 bits compiler from Platform SDK,
+ which is NOT a beta, and compile using the Visual studio 2005 IDE
+see http://www.winimage.com/misc/sdk64onvs2005/ for instruction
+
+- Uncompress current zlib, including all contrib/* files
+- start Visual Studio 2005 from a platform SDK command prompt, using
+ the /useenv switch
+- Open contrib\vstudio\vc8\zlibvc.sln with Microsoft Visual C++ 8.0
+
+
+Important
+---------
+- To use zlibwapi.dll in your application, you must define the
+ macro ZLIB_WINAPI when compiling your application's source files.
+
+
+Additional notes
+----------------
+- This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built
+ by Gilles Vollant from the zlib 1.1.x sources, and distributed at
+ http://www.winimage.com/zLibDll
+ It uses the WINAPI calling convention for the exported functions, and
+ includes the minizip functionality. If your application needs that
+ particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll.
+
+- The new DLL was renamed because there exist several incompatible
+ versions of zlib.dll on the Internet.
+
+- There is also an official DLL build of zlib, named zlib1.dll. This one
+ is exporting the functions using the CDECL convention. See the file
+ win32\DLL_FAQ.txt found in this zlib distribution.
+
+- There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol
+ has a slightly different effect. To avoid compatibility problems, do
+ not define it here.
+

+/* + * ALGORITHM + * + * The "deflation" process depends on being able to identify portions + * of the input text which are identical to earlier input (within a + * sliding window trailing behind the input currently being processed). + * + * The most straightforward technique turns out to be the fastest for + * most input files: try all possible matches and select the longest. + * The key feature of this algorithm is that insertions into the string + * dictionary are very simple and thus fast, and deletions are avoided + * completely. Insertions are performed at each input character, whereas + * string matches are performed only when the previous match ends. So it + * is preferable to spend more time in matches to allow very fast string + * insertions and avoid deletions. The matching algorithm for small + * strings is inspired from that of Rabin & Karp. A brute force approach + * is used to find longer strings when a small match has been found. + * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze + * (by Leonid Broukhis). + * A previous version of this file used a more sophisticated algorithm + * (by Fiala and Greene) which is guaranteed to run in linear amortized + * time, but has a larger average cost, uses more memory and is patented. + * However the F&G algorithm may be faster for some highly redundant + * files if the parameter max_chain_length (described below) is too large. + * + * ACKNOWLEDGEMENTS + * + * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and + * I found it in 'freeze' written by Leonid Broukhis. + * Thanks to many people for bug reports and testing. + * + * REFERENCES + * + * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". + * Available in http://www.ietf.org/rfc/rfc1951.txt + * + * A description of the Rabin and Karp algorithm is given in the book + * "Algorithms" by R.

The first pass generates + enough deflate blocks to produce output to fill the requested + output size plus a specfied excess amount (see the EXCESS define + below). The last deflate block may go quite a bit past that, but + is discarded. The second pass decompresses and recompresses just + the compressed data that fit in the requested plus excess sized + buffer. The deflate process is terminated after that amount of + input, which is less than the amount consumed on the first pass. + The last deflate block of the result will be of a comparable size + to the final product, so that the header for that deflate block and + the compression ratio for that block will be about the same as in + the final product. The third compression pass decompresses the + result of the second step, but only the compressed data up to the + requested size minus an amount to allow the compressed stream to + complete (see the MARGIN define below). That will result in a + final compressed stream whose length is less than or equal to the + requested size. Assuming sufficient input and a requested size + greater than a few hundred bytes, the shortfall will typically be + less than ten bytes. + + If the input is short enough that the first compression completes + before filling the requested output size, then that compressed + stream is return with no recompression. + + EXCESS is chosen to be just greater than the shortfall seen in a + two pass approach similar to the above. That shortfall is due to + the last deflate block compressing more efficiently with a smaller + header on the second pass. EXCESS is set to be large enough so + that there is enough uncompressed data for the second pass to fill + out the requested size, and small enough so that the final deflate + block of the second pass will be close in size to the final deflate + block of the third and final pass.

The gzip file is written to directly, to + avoid copying that file, in case it's large. Note that this results in the + unfriendly behavior that if gzappend fails, the gzip file is corrupted. + + This program was written to illustrate the use of the new Z_BLOCK option of + zlib 1.2.x's inflate() function. This option returns from inflate() at each + block boundary to facilitate locating and modifying the last block bit at + the start of the final deflate block. Also whether using Z_BLOCK or not, + another required feature of zlib 1.2.x is that inflate() now provides the + number of unusued bits in the last input byte used. gzappend will not work + with versions of zlib earlier than 1.2.1. + + gzappend first decompresses the gzip file internally, discarding all but + the last 32K of uncompressed data, and noting the location of the last block + bit and the number of unused bits in the last byte of the compressed data. + The gzip trailer containing the CRC-32 and length of the uncompressed data + is verified. This trailer will be later overwritten. + + Then the last block bit is cleared by seeking back in the file and rewriting + the byte that contains it. Seeking forward, the last byte of the compressed + data is saved along with the number of unused bits to initialize deflate. + + A deflate process is initialized, using the last 32K of the uncompressed + data from the gzip file to initialize the dictionary. If the total + uncompressed data was less than 32K, then all of it is used to initialize + the dictionary. The deflate output bit buffer is also initialized with the + last bits from the original deflate stream. From here on, the data to + append is simply compressed using deflate, and written to the gzip file. + When that is complete, the new CRC-32 and uncompressed length are written + as the trailer of the gzip file. + */ + +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <fcntl.h> +#include <unistd.h> +#include "zlib.h" + +#define local static +#define LGCHUNK 14 +#define CHUNK (1U << LGCHUNK) +#define DSIZE 32768U + +/* print an error message and terminate with extreme prejudice */ +local void bye(char *msg1, char *msg2) +{ + fprintf(stderr, "gzappend error: %s%s\n", msg1, msg2);

The <em>zlib</em> constant Z_DEFAULT_COMPRESSION, +equal to -1, +provides a good compromise between compression and speed and is equivalent to level 6. +Level 0 actually does no compression at all, and in fact expands the data slightly to produce +the <em>zlib</em> format (it is not a byte-for-byte copy of the input). +More advanced applications of <em>zlib</em> +may use <tt>deflateInit2()</tt> here instead.

This +is especially important for environments in which <em>zlib</em> is a shared library. +<p> +Note that an application can initialize multiple, independent <em>zlib</em> streams, which can +operate in parallel.

The outer <tt>do</tt>-loop +reads all of the input file and exits at the bottom of the loop once end-of-file is reached. +This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the +input data has been processed and that all of the output data has been generated and consumed +before we fall out of the loop at the bottom. +<pre><b> + /* compress until end of file */ + do { +</b></pre> +We start off by reading data from the input file. The number of bytes read is put directly +into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also +check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the +<em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to +indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt> +to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The +reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss +the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish +up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em> +constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still +in the middle of the uncompressed data. +<p> +If there is an error in reading from the input file, the process is aborted with +<tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning +the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called +at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or +<tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is +no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail. +<pre><b> + strm.avail_in = fread(in, 1, CHUNK, source); + if (ferror(source)) { + (void)deflateEnd(&strm); + return Z_ERRNO; + } + flush = feof(source) ?

Once there is no more +new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e., +<tt>avail_in</tt> will be zero. +<pre><b> + /* run deflate() on input until output buffer not full, finish + compression if all of source has been read in */ + do { +</b></pre> +Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number +of available output bytes and <tt>next_out</tt> to a pointer to that space. +<pre><b> + strm.avail_out = CHUNK; + strm.next_out = out; +</b></pre> +Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the +<tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as +<tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then +updated past the input data consumed and the output data written. It is the amount of +output space available that may limit how much input is consumed. +Hence the inner loop to make sure that +all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt> +and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those +between <tt>deflate()</tt> calls until it's all used up. +<p> +The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing +the input and output information and the internal compression engine state, and a parameter +indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume +several K bytes of input data before producing any output (except for the header), in order +to accumulate statistics on the data for optimum compression. It will then put out a burst of +compressed data, and proceed to consume more input before the next burst. Eventually, +<tt>deflate()</tt> +must be told to terminate the stream, complete the compression with provided input data, and +write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long +as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided, +<tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how +much output space is provided, <tt>deflate()</tt> may have to be called several times until it +has provided the complete compressed stream, even after it has consumed all of the input. The flush +parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls. +<p> +There are other values of the flush parameter that are used in more advanced applications. You can +force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided +so far, even if it wouldn't have otherwise, for example to control data latency on a link with +compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to +that point so that what follows can be decompressed independently, for example for random access +applications. Both requests will degrade compression by an amount depending on how often such +requests are made. +<p> +<tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why +not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through +<tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are +<tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt> +is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of +<tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt> +until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not +initialized properly, but we did initialize it properly. There is no harm in checking for +<tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some +other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state. +<tt>Z_BUF_ERROR</tt> will be explained further below, but +suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume +more input or produce more output. <tt>deflate()</tt> can be called again with more output space +or more available input, which it will be in this code. +<pre><b> + ret = deflate(&strm, flush); /* no bad return value */ + assert(ret != Z_STREAM_ERROR); /* state not clobbered */ +</b></pre> +Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the +difference between how much space was provided before the call, and how much output space +is still available after the call. Then that data, if any, is written to the output file. +We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there +is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak. +<pre><b> + have = CHUNK - strm.avail_out; + if (fwrite(out, 1, have, dest) != have || ferror(dest)) { + (void)deflateEnd(&strm); + return Z_ERRNO; + } +</b></pre> +The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the +provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with +the provided input, and that all of that input has been consumed. We can then fall out of this +loop and reuse the input buffer. +<p> +The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill +the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that +<tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer! +<tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can. +As far as we know, <tt>deflate()</tt> +has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output +at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call +wasn't able to do anything, either consume input or produce output, and so it returns +<tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at +all. Now we finally have the desired indication that <tt>deflate()</tt> is really done, +and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>. +<p> +With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will +complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return +<tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing +until the state is reinitialized. +<p> +Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt> +instead of the single inner loop we have here. The first loop would call +without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call +<tt>deflate()</tt> with no more +data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this +example, that can be avoided by simply keeping track of the current flush state. +<pre><b> + } while (strm.avail_out == 0); + assert(strm.avail_in == 0); /* all input will be used */ +</b></pre><!-- --> +Now we check to see if we have already processed all of the input file. That information was +saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so, +then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt> +from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was +consumed and all of the output was generated. +<pre><b> + /* done when last data in file processed */ + } while (flush != Z_FINISH); + assert(ret == Z_STREAM_END); /* stream will be complete */ +</b></pre><!-- --> +The process is complete, but we still need to deallocate the state to avoid a memory leak +(or rather more like a memory hemorrhage if you didn't do this). Then +finally we can return with a happy return value. +<pre><b> + /* clean up and return */ + (void)deflateEnd(&strm); + return Z_OK; +} +</b></pre><!-- --> +Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt> +decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the +uncompressed data to the output file. Much of the discussion above for <tt>def()</tt> +applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between +the two. +<pre><b> +/* Decompress from file source to file dest until stream ends or EOF. + inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be + allocated for processing, Z_DATA_ERROR if the deflate data is + invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and + the version of the library linked do not match, or Z_ERRNO if there + is an error reading or writing the files. */ +int inf(FILE *source, FILE *dest) +{ +</b></pre> +The local variables have the same functionality as they do for <tt>def()</tt>. The +only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt> +can tell from the <em>zlib</em> stream itself when the stream is complete. +<pre><b> + int ret; + unsigned have; + z_stream strm; + char in[CHUNK]; + char out[CHUNK]; +</b></pre><!-- --> +The initialization of the state is the same, except that there is no compression level, +of course, and two more elements of the structure are initialized. <tt>avail_in</tt> +and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This +is because the application has the option to provide the start of the zlib stream in +order for <tt>inflateInit()</tt> to have access to information about the compression +method to aid in memory allocation. In the current implementation of <em>zlib</em> +(up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of +<tt>inflate()</tt> anyway.

A file containing a zlib or gzip + stream is provided on the command line. The compressed stream is decoded in + its entirety, and an index built with access points about every SPAN bytes + in the uncompressed output. The compressed file is left open, and can then + be read randomly, having to decompress on the average SPAN/2 uncompressed + bytes before getting to the desired block of data. + + An access point can be created at the start of any deflate block, by saving + the starting file offset and bit of that block, and the 32K bytes of + uncompressed data that precede that block. Also the uncompressed offset of + that block is saved to provide a referece for locating a desired starting + point in the uncompressed stream. build_index() works by decompressing the + input zlib or gzip stream a block at a time, and at the end of each block + deciding if enough uncompressed data has gone by to justify the creation of + a new access point. If so, that point is saved in a data structure that + grows as needed to accommodate the points. + + To use the index, an offset in the uncompressed data is provided, for which + the latest accees point at or preceding that offset is located in the index. + The input file is positioned to the specified location in the index, and if + necessary the first few bits of the compressed data is read from the file. + inflate is initialized with those bits and the 32K of uncompressed data, and + the decompression then proceeds until the desired offset in the file is + reached. Then the decompression continues to read the desired uncompressed + data from the file. + + Another approach would be to generate the index on demand. In that case, + requests for random access reads from the compressed data would try to use + the index, but if a read far enough past the end of the index is required, + then further index entries would be generated and added. + + There is some fair bit of overhead to starting inflation for the random + access, mainly copying the 32K byte dictionary. So if small pieces of the + file are being accessed, it would make sense to implement a cache to hold + some lookahead and avoid many calls to extract() for small lengths. + + Another way to build an index would be to use inflateCopy(). That would + not be constrained to have access points at block boundaries, but requires + more memory per access point, and also cannot be saved to file due to the + use of pointers in the state.

Nov 2002 + * - First version -- complete rewrite of inflate to simplify code, avoid + * creation of window when not needed, minimize use of window when it is + * needed, make inffast.c even faster, implement gzip decoding, and to + * improve code readability and style over the previous zlib inflate code + * + * 1.2.beta1 25 Nov 2002 + * - Use pointers for available input and output checking in inffast.c + * - Remove input and output counters in inffast.c + * - Change inffast.c entry and loop from avail_in >= 7 to >= 6 + * - Remove unnecessary second byte pull from length extra in inffast.c + * - Unroll direct copy to three copies per loop in inffast.c + * + * 1.2.beta2 4 Dec 2002 + * - Change external routine names to reduce potential conflicts + * - Correct filename to inffixed.h for fixed tables in inflate.c + * - Make hbuf[] unsigned char to match parameter type in inflate.c + * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset) + * to avoid negation problem on Alphas (64 bit) in inflate.c + * + * 1.2.beta3 22 Dec 2002 + * - Add comments on state->bits assertion in inffast.c + * - Add comments on op field in inftrees.h + * - Fix bug in reuse of allocated window after inflateReset() + * - Remove bit fields--back to byte structure for speed + * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths + * - Change post-increments to pre-increments in inflate_fast(), PPC biased? + * - Add compile time option, POSTINC, to use post-increments instead (Intel?) + * - Make MATCH copy in inflate() much faster for when inflate_fast() not used + * - Use local copies of stream next and avail values, as well as local bit + * buffer and bit count in inflate()--for speed when inflate_fast() not used + * + * 1.2.beta4 1 Jan 2003 + * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings + * - Move a comment on output buffer sizes from inffast.c to inflate.c + * - Add comments in inffast.c to introduce the inflate_fast() routine + * - Rearrange window copies in inflate_fast() for speed and simplification + * - Unroll last copy for window match in inflate_fast() + * - Use local copies of window variables in inflate_fast() for speed + * - Pull out common write == 0 case for speed in inflate_fast() + * - Make op and len in inflate_fast() unsigned for consistency + * - Add FAR to lcode and dcode declarations in inflate_fast() + * - Simplified bad distance check in inflate_fast() + * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new + * source file infback.c to provide a call-back interface to inflate for + * programs like gzip and unzip -- uses window as output buffer to avoid + * window copying + * + * 1.2.beta5 1 Jan 2003 + * - Improved inflateBack() interface to allow the caller to provide initial + * input in strm. + * - Fixed stored blocks bug in inflateBack() + * + * 1.2.beta6 4 Jan 2003 + * - Added comments in inffast.c on effectiveness of POSTINC + * - Typecasting all around to reduce compiler warnings + * - Changed loops from while (1) or do {} while (1) to for (;;), again to + * make compilers happy + * - Changed type of window in inflateBackInit() to unsigned char * + * + * 1.2.beta7 27 Jan 2003 + * - Changed many types to unsigned or unsigned short to avoid warnings + * - Added inflateCopy() function + * + * 1.2.0 9 Mar 2003 + * - Changed inflateBack() interface to provide separate opaque descriptors + * for the in() and out() functions + * - Changed inflateBack() argument and in_func typedef to swap the length + * and buffer address return values for the input function + * - Check next_in and next_out for Z_NULL on entry to inflate() + * + * The history for versions after 1.2.0 are in ChangeLog in zlib

The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available.

This version of the library supports only one compression method + (deflation) but other algorithms will be added later and will have the same + stream interface. + <p> + + Compression can be done in a single step if the buffers are large + enough (for example if an input file is mmap'ed), or can be done by + repeated calls of the compression function. In the latter case, the + application must provide more input and/or consume the output + (providing more output space) before each call. + <p> + + The library also supports reading and writing files in gzip (.gz) format + with an interface similar to that of stdio. + <p> + + The library does not install any signal handler.

If you have +general questions about zlib, you should see the file "FAQ" found +in the zlib distribution, or at the following location: + http://www.gzip.org/zlib/zlib_faq.html + + + 1. What is ZLIB1.DLL, and how can I get it? + + - ZLIB1.DLL is the official build of zlib as a DLL. + (Please remark the character '1' in the name.) + + Pointers to a precompiled ZLIB1.DLL can be found in the zlib + web site at: + http://www.zlib.org/ + + Applications that link to ZLIB1.DLL can rely on the following + specification: + + * The exported symbols are exclusively defined in the source + files "zlib.h" and "zlib.def", found in an official zlib + source distribution. + * The symbols are exported by name, not by ordinal. + * The exported names are undecorated. + * The calling convention of functions is "C" (CDECL). + * The ZLIB1.DLL binary is linked to MSVCRT.DLL. + + The archive in which ZLIB1.DLL is bundled contains compiled + test programs that must run with a valid build of ZLIB1.DLL. + It is recommended to download the prebuilt DLL from the zlib + web site, instead of building it yourself, to avoid potential + incompatibilities that could be introduced by your compiler + and build settings. If you do build the DLL yourself, please + make sure that it complies with all the above requirements, + and it runs with the precompiled test programs, bundled with + the original ZLIB1.DLL distribution. + + If, for any reason, you need to build an incompatible DLL, + please use a different file name. + + + 2. Why did you change the name of the DLL to ZLIB1.DLL? + What happened to the old ZLIB.DLL? + + - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required + compilation settings that were incompatible to those used by + a static build. The DLL settings were supposed to be enabled + by defining the macro ZLIB_DLL, before including "zlib.h". + Incorrect handling of this macro was silently accepted at + build time, resulting in two major problems: + + * ZLIB_DLL was missing from the old makefile. When building + the DLL, not all people added it to the build options. In + consequence, incompatible incarnations of ZLIB.DLL started + to circulate around the net. + + * When switching from using the static library to using the + DLL, applications had to define the ZLIB_DLL macro and + to recompile all the sources that contained calls to zlib + functions. Failure to do so resulted in creating binaries + that were unable to run with the official ZLIB.DLL build. + + The only possible solution that we could foresee was to make + a binary-incompatible change in the DLL interface, in order to + remove the dependency on the ZLIB_DLL macro, and to release + the new DLL under a different name. + + We chose the name ZLIB1.DLL, where '1' indicates the major + zlib version number. We hope that we will not have to break + the binary compatibility again, at least not as long as the + zlib-1.x series will last. + + There is still a ZLIB_DLL macro, that can trigger a more + efficient build and use of the DLL, but compatibility no + longer dependents on it. + + + 3. Can I build ZLIB.DLL from the new zlib sources, and replace + an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier? + + - In principle, you can do it by assigning calling convention + keywords to the macros ZEXPORT and ZEXPORTVA. In practice, + it depends on what you mean by "an old ZLIB.DLL", because the + old DLL exists in several mutually-incompatible versions. + You have to find out first what kind of calling convention is + being used in your particular ZLIB.DLL build, and to use the + same one in the new build. If you don't know what this is all + about, you might be better off if you would just leave the old + DLL intact. + + + 4. Can I compile my application using the new zlib interface, and + link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or + earlier? + + - The official answer is "no"; the real answer depends again on + what kind of ZLIB.DLL you have. Even if you are lucky, this + course of action is unreliable. + + If you rebuild your application and you intend to use a newer + version of zlib (post- 1.1.4), it is strongly recommended to + link it to the new ZLIB1.DLL. + + + 5. Why are the zlib symbols exported by name, and not by ordinal? + + - Although exporting symbols by ordinal is a little faster, it + is risky. Any single glitch in the maintenance or use of the + DEF file that contains the ordinals can result in incompatible + builds and frustrating crashes. Simply put, the benefits of + exporting symbols by ordinal do not justify the risks. + + Technically, it should be possible to maintain ordinals in + the DEF file, and still export the symbols by name. Ordinals + exist in every DLL, and even if the dynamic linking performed + at the DLL startup is searching for names, ordinals serve as + hints, for a faster name lookup. However, if the DEF file + contains ordinals, the Microsoft linker automatically builds + an implib that will cause the executables linked to it to use + those ordinals, and not the names. It is interesting to + notice that the GNU linker for Win32 does not suffer from this + problem. + + It is possible to avoid the DEF file if the exported symbols + are accompanied by a "__declspec(dllexport)" attribute in the + source files. You can do this in zlib by predefining the + ZLIB_DLL macro. + + + 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling + convention. Why not use the STDCALL convention? + STDCALL is the standard convention in Win32, and I need it in + my Visual Basic project! + + (For readability, we use CDECL to refer to the convention + triggered by the "__cdecl" keyword, STDCALL to refer to + the convention triggered by "__stdcall", and FASTCALL to + refer to the convention triggered by "__fastcall".) + + - Most of the native Windows API functions (without varargs) use + indeed the WINAPI convention (which translates to STDCALL in + Win32), but the standard C functions use CDECL. If a user + application is intrinsically tied to the Windows API (e.g. + it calls native Windows API functions such as CreateFile()), + sometimes it makes sense to decorate its own functions with + WINAPI. But if ANSI C or POSIX portability is a goal (e.g. + it calls standard C functions such as fopen()), it is not a + sound decision to request the inclusion of <windows.h>, or to + use non-ANSI constructs, for the sole purpose to make the user + functions STDCALL-able. + + The functionality offered by zlib is not in the category of + "Windows functionality", but is more like "C functionality". + + Technically, STDCALL is not bad; in fact, it is slightly + faster than CDECL, and it works with variable-argument + functions, just like CDECL. It is unfortunate that, in spite + of using STDCALL in the Windows API, it is not the default + convention used by the C compilers that run under Windows. + The roots of the problem reside deep inside the unsafety of + the K&R-style function prototypes, where the argument types + are not specified; but that is another story for another day. + + The remaining fact is that CDECL is the default convention. + Even if an explicit convention is hard-coded into the function + prototypes inside C headers, problems may appear. The + necessity to expose the convention in users' callbacks is one + of these problems. + + The calling convention issues are also important when using + zlib in other programming languages. Some of them, like Ada + (GNAT) and Fortran (GNU G77), have C bindings implemented + initially on Unix, and relying on the C calling convention. + On the other hand, the pre- .NET versions of Microsoft Visual + Basic require STDCALL, while Borland Delphi prefers, although + it does not require, FASTCALL. + + In fairness to all possible uses of zlib outside the C + programming language, we choose the default "C" convention. + Anyone interested in different bindings or conventions is + encouraged to maintain specialized projects. The "contrib/" + directory from the zlib distribution already holds a couple + of foreign bindings, such as Ada, C++, and Delphi. + + + 7. I need a DLL for my Visual Basic project. What can I do? + + - Define the ZLIB_WINAPI macro before including "zlib.h", when + building both the DLL and the user application (except that + you don't need to define anything when using the DLL in Visual + Basic). The ZLIB_WINAPI macro will switch on the WINAPI + (STDCALL) convention. The name of this DLL must be different + than the official ZLIB1.DLL. + + Gilles Vollant has contributed a build named ZLIBWAPI.DLL, + with the ZLIB_WINAPI macro turned on, and with the minizip + functionality built in. For more information, please read + the notes inside "contrib/vstudio/readme.txt", found in the + zlib distribution. + + + 8. I need to use zlib in my Microsoft .NET project. What can I + do? + + - Henrik Ravn has contributed a .NET wrapper around zlib. Look + into contrib/dotzlib/, inside the zlib distribution. + + + 9. If my application uses ZLIB1.DLL, should I link it to + MSVCRT.DLL? Why? + + - It is not required, but it is recommended to link your + application to MSVCRT.DLL, if it uses ZLIB1.DLL. + + The executables (.EXE, .DLL, etc.) that are involved in the + same process and are using the C run-time library (i.e. they + are calling standard C functions), must link to the same + library. There are several libraries in the Win32 system: + CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc. + Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that + depend on it should also be linked to MSVCRT.DLL. + + +10. Why are you saying that ZLIB1.DLL and my application should + be linked to the same C run-time (CRT) library? I linked my + application and my DLLs to different C libraries (e.g. my + application to a static library, and my DLLs to MSVCRT.DLL), + and everything works fine. + + - If a user library invokes only pure Win32 API (accessible via + <windows.h> and the related headers), its DLL build will work + in any context. But if this library invokes standard C API, + things get more complicated. + + There is a single Win32 library in a Win32 system. Every + function in this library resides in a single DLL module, that + is safe to call from anywhere. On the other hand, there are + multiple versions of the C library, and each of them has its + own separate internal state. Standalone executables and user + DLLs that call standard C functions must link to a C run-time + (CRT) library, be it static or shared (DLL). Intermixing + occurs when an executable (not necessarily standalone) and a + DLL are linked to different CRTs, and both are running in the + same process. + + Intermixing multiple CRTs is possible, as long as their + internal states are kept intact. The Microsoft Knowledge Base + articles KB94248 "HOWTO: Use the C Run-Time" and KB140584 + "HOWTO: Link with the Correct C Run-Time (CRT) Library" + mention the potential problems raised by intermixing. + + If intermixing works for you, it's because your application + and DLLs are avoiding the corruption of each of the CRTs' + internal states, maybe by careful design, or maybe by fortune. + + Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such + as those provided by Borland, raises similar problems. + + +11. Why are you linking ZLIB1.DLL to MSVCRT.DLL? + + - MSVCRT.DLL exists on every Windows 95 with a new service pack + installed, or with Microsoft Internet Explorer 4 or later, and + on all other Windows 4.x or later (Windows 98, Windows NT 4, + or later). It is freely distributable; if not present in the + system, it can be downloaded from Microsoft or from other + software provider for free. + + The fact that MSVCRT.DLL does not exist on a virgin Windows 95 + is not so problematic. Windows 95 is scarcely found nowadays, + Microsoft ended its support a long time ago, and many recent + applications from various vendors, including Microsoft, do not + even run on it. Furthermore, no serious user should run + Windows 95 without a proper update installed. + + +12. Why are you not linking ZLIB1.DLL to + <<my favorite C run-time library>> ? + + - We considered and abandoned the following alternatives: + + * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or + LIBCMT.LIB) is not a good option. People are using the DLL + mainly to save disk space. If you are linking your program + to a static C library, you may as well consider linking zlib + in statically, too. + + * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because + CRTDLL.DLL is present on every Win32 installation. + Unfortunately, it has a series of problems: it does not + work properly with Microsoft's C++ libraries, it does not + provide support for 64-bit file offsets, (and so on...), + and Microsoft discontinued its support a long time ago. + + * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied + with the Microsoft .NET platform, and Visual C++ 7.0/7.1, + raises problems related to the status of ZLIB1.DLL as a + system component. According to the Microsoft Knowledge Base + article KB326922 "INFO: Redistribution of the Shared C + Runtime Component in Visual C++ .NET", MSVCR70.DLL and + MSVCR71.DLL are not supposed to function as system DLLs, + because they may clash with MSVCRT.DLL. Instead, the + application's installer is supposed to put these DLLs + (if needed) in the application's private directory. + If ZLIB1.DLL depends on a non-system runtime, it cannot + function as a redistributable system component. + + * Linking ZLIB1.DLL to non-Microsoft runtimes, such as + Borland's, or Cygwin's, raises problems related to the + reliable presence of these runtimes on Win32 systems. + It's easier to let the DLL build of zlib up to the people + who distribute these runtimes, and who may proceed as + explained in the answer to Question 14. + + +13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL, + how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0 + (Visual Studio .NET) or newer? + + - Due to the problems explained in the Microsoft Knowledge Base + article KB326922 (see the previous answer), the C runtime that + comes with the VC7 environment is no longer considered a + system component. That is, it should not be assumed that this + runtime exists, or may be installed in a system directory. + Since ZLIB1.DLL is supposed to be a system component, it may + not depend on a non-system component. + + In order to link ZLIB1.DLL and your application to MSVCRT.DLL + in VC7, you need the library of Visual C++ 6.0 or older. If + you don't have this library at hand, it's probably best not to + use ZLIB1.DLL. + + We are hoping that, in the future, Microsoft will provide a + way to build applications linked to a proper system runtime, + from the Visual C++ environment. Until then, you have a + couple of alternatives, such as linking zlib in statically. + If your application requires dynamic linking, you may proceed + as explained in the answer to Question 14. + + +14. I need to link my own DLL build to a CRT different than + MSVCRT.DLL. What can I do? + + - Feel free to rebuild the DLL from the zlib sources, and link + it the way you want. You should, however, clearly state that + your build is unofficial. You should give it a different file + name, and/or install it in a private directory that can be + accessed by your application only, and is not visible to the + others (e.g. it's not in the SYSTEM or the SYSTEM32 directory, + and it's not in the PATH). Otherwise, your build may clash + with applications that link to the official build. + + For example, in Cygwin, zlib is linked to the Cygwin runtime + CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL. + + +15. May I include additional pieces of code that I find useful, + link them in ZLIB1.DLL, and export them? + + - No. A legitimate build of ZLIB1.DLL must not include code + that does not originate from the official zlib source code. + But you can make your own private DLL build, under a different + file name, as suggested in the previous answer. + + For example, zlib is a part of the VCL library, distributed + with Borland Delphi and C++ Builder. The DLL build of VCL + is a redistributable file, named VCLxx.DLL. + + +16. May I remove some functionality out of ZLIB1.DLL, by enabling + macros like NO_GZCOMPRESS or NO_GZIP at compile time? + + - No. A legitimate build of ZLIB1.DLL must provide the complete + zlib functionality, as implemented in the official zlib source + code. But you can make your own private DLL build, under a + different file name, as suggested in the previous answer. + + +17. I made my own ZLIB1.DLL build. Can I test it for compliance? + + - We prefer that you download the official DLL from the zlib + web site. If you need something peculiar from this DLL, you + can send your suggestion to the zlib mailing list. + + However, in case you do rebuild the DLL yourself, you can run + it with the test programs found in the DLL distribution. + Running these test programs is not a guarantee of compliance, + but a failure can imply a detected problem. + +** + +This document is written and maintained by +Cosmin Truta <cosmint@cs.ubbcluj.ro> diff --git a/funtools/util/zlib-1.2.3/win32/Makefile.bor b/funtools/util/zlib-1.2.3/win32/Makefile.bor new file mode 100644 index 0000000..b802519 --- /dev/null +++ b/funtools/util/zlib-1.2.3/win32/Makefile.bor @@ -0,0 +1,107 @@ +# Makefile for zlib +# Borland C++ for Win32 +# +# Updated for zlib 1.2.x by Cosmin Truta, 11-Mar-2003 +# Last updated: 28-Aug-2003 +# +# Usage: +# make -f win32/Makefile.bor +# make -f win32/Makefile.bor LOCAL_ZLIB=-DASMV OBJA=match.obj OBJPA=+match.obj + +# ------------ Borland C++ ------------ + +# Optional nonstandard preprocessor flags (e.g. -DMAX_MEM_LEVEL=7) +# should be added to the environment via "set LOCAL_ZLIB=-DFOO" or +# added to the declaration of LOC here: +LOC = $(LOCAL_ZLIB) + +CC = bcc32 +AS = bcc32 +LD = bcc32 +AR = tlib +CFLAGS = -a -d -k- -O2 $(LOC) +ASFLAGS = $(LOC) +LDFLAGS = $(LOC) + + +# variables +ZLIB_LIB = zlib.lib + +OBJ1 = adler32.obj compress.obj crc32.obj deflate.obj gzio.obj infback.obj +OBJ2 = inffast.obj inflate.obj inftrees.obj trees.obj uncompr.obj zutil.obj +#OBJA = +OBJP1 = +adler32.obj+compress.obj+crc32.obj+deflate.obj+gzio.obj+infback.obj +OBJP2 = +inffast.obj+inflate.obj+inftrees.obj+trees.obj+uncompr.obj+zutil.obj +#OBJPA= + + +# targets +all: $(ZLIB_LIB) example.exe minigzip.exe + +.c.obj: + $(CC) -c $(CFLAGS) $< + +.asm.obj: + $(AS) -c $(ASFLAGS) $< + +adler32.obj: adler32.c zlib.h zconf.h + +compress.obj: compress.c zlib.h zconf.h + +crc32.obj: crc32.c zlib.h zconf.h crc32.h + +deflate.obj: deflate.c deflate.h zutil.h zlib.h zconf.h + +gzio.obj: gzio.c zutil.h zlib.h zconf.h + +infback.obj: infback.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ + inffast.h inffixed.h + +inffast.obj: inffast.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ + inffast.h + +inflate.obj: inflate.c zutil.h zlib.h zconf.h inftrees.h inflate.h \ + inffast.h inffixed.h + +inftrees.obj: inftrees.c zutil.h zlib.h zconf.h inftrees.h + +trees.obj: trees.c zutil.h zlib.h zconf.h deflate.h trees.h + +uncompr.obj: uncompr.c zlib.h zconf.h + +zutil.obj: zutil.c zutil.h zlib.h zconf.h + +example.obj: example.c zlib.h zconf.h + +minigzip.obj: minigzip.c zlib.h zconf.h + + +# For the sake of the old Borland make, +# the command line is cut to fit in the MS-DOS 128 byte limit: +$(ZLIB_LIB): $(OBJ1) $(OBJ2) $(OBJA) + -del $(ZLIB_LIB) + $(AR) $(ZLIB_LIB) $(OBJP1) + $(AR) $(ZLIB_LIB) $(OBJP2) + $(AR) $(ZLIB_LIB) $(OBJPA) + + +# testing +test: example.exe minigzip.exe + example + echo hello world | minigzip | minigzip -d + +example.exe: example.obj $(ZLIB_LIB) + $(LD) $(LDFLAGS) example.obj $(ZLIB_LIB) + +minigzip.exe: minigzip.obj $(ZLIB_LIB) + $(LD) $(LDFLAGS) minigzip.obj $(ZLIB_LIB) + + +# cleanup +clean: + -del *.obj + -del *.lib + -del *.exe + -del *.tds + -del zlib.bak + -del foo.gz diff --git a/funtools/util/zlib-1.2.3/win32/Makefile.emx b/funtools/util/zlib-1.2.3/win32/Makefile.emx new file mode 100644 index 0000000..7b08424 --- /dev/null +++ b/funtools/util/zlib-1.2.3/win32/Makefile.emx @@ -0,0 +1,69 @@ +# Makefile for zlib.
