- strm provides the memory allocation functions and window buffer on input,
- and provides information on the unused input on return. For Z_DATA_ERROR
- returns, strm will also provide an error message.
-
- in() and out() are the call-back input and output functions. When
- inflateBack() needs more input, it calls in(). When inflateBack() has
- filled the window with output, or when it completes with data in the
- window, it calls out() to write out the data. The application must not
- change the provided input until in() is called again or inflateBack()
- returns. The application must not change the window/output buffer until
- inflateBack() returns.
-
- in() and out() are called with a descriptor parameter provided in the
- inflateBack() call. This parameter can be a structure that provides the
- information required to do the read or write, as well as accumulated
- information on the input and output such as totals and check values.
-
- in() should return zero on failure. out() should return non-zero on
- failure. If either in() or out() fails, than inflateBack() returns a
- Z_BUF_ERROR. strm->next_in can be checked for Z_NULL to see whether it
- was in() or out() that caused in the error. Otherwise, inflateBack()
- returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
- error, or Z_MEM_ERROR if it could not allocate memory for the state.
- inflateBack() can also return Z_STREAM_ERROR if the input parameters
- are not correct, i.e. strm is Z_NULL or the state was not initialized.

- Process a set of code lengths to create a canonical Huffman code. The
- code lengths are lens[0..codes-1]. Each length corresponds to the
- symbols 0..codes-1. The Huffman code is generated by first sorting the
- symbols by length from short to long, and retaining the symbol order
- for codes with equal lengths. Then the code starts with all zero bits
- for the first code of the shortest length, and the codes are integer
- increments for the same length, and zeros are appended as the length
- increases. For the deflate format, these bits are stored backwards
- from their more natural integer increment ordering, and so when the
- decoding tables are built in the large loop below, the integer codes
- are incremented backwards.
-
- This routine assumes, but does not check, that all of the entries in
- lens[] are in the range 0..MAXBITS. The caller must assure this.
- 1..MAXBITS is interpreted as that code length. zero means that that
- symbol does not occur in this code.
-
- The codes are sorted by computing a count of codes for each length,
- creating from that a table of starting indices for each length in the
- sorted table, and then entering the symbols in order in the sorted
- table. The sorted table is work[], with that space being provided by
- the caller.
-
- The length counts are used for other purposes as well, i.e. finding
- the minimum and maximum length codes, determining if there are any
- codes at all, checking for a valid set of lengths, and looking ahead
- at length counts to determine sub-table sizes when building the

- Create and fill in decoding tables. In this loop, the table being

- with length len. That code is converted to an index by dropping drop
- bits off of the bottom. For codes where len is less than drop + curr,
- those top drop + curr - len bits are incremented through all values to
- fill the table with replicated entries.
-
- root is the number of index bits for the root table. When len exceeds
- root, sub-tables are created pointed to by the root entry with an index
- of the low root bits of huff. This is saved in low to check for when a
- new sub-table should be started. drop is zero when the root table is
- being filled, and drop is root when sub-tables are being filled.
-
- When a new sub-table is needed, it is necessary to look ahead in the
- code lengths to determine what size sub-table is needed. The length
- counts are used for this, and so count[] is decremented as codes are
- entered in the tables.
-
- used keeps track of how many table entries have been allocated from the
- provided *table space. It is checked for LENS and DIST tables against
- the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
- the initial root table size constants. See the comments in inftree9.h
- for more information.
-
- sym increments through all symbols, and the loop terminates when
- all codes of length max, i.e. all codes, have been processed. This

- in the rest of the decoding tables with invalid code markers.
