The first is an array of 'struct argument' items, the + second array has 'void *' entried. + + 5.

For each arg, ConvParam stores the contained C data (or a pointer to it, + for structures) into the 'struct argument' array. + + 7. Finally, a loop fills the 'void *' array so that each item points to the + data contained in or pointed to by the 'struct argument' array. + + 8.

It can be configured to yield a warning +when trying to close it (dynamic libraries cannot currently be unloaded). + +It automatically searches for modules in several directories when no +absolute path is specified and the module is not found in the current +directory. + +The paths searched are those specified in the environment variables +LD_LIBRARY_PATH and DYLD_LIBRARY_PATH plus /lib, /usr/local/lib and +/usr/lib or the path specified in the environment variable +DYLD_FALLBACK_LIBRARY_PATH. + +In the default install the behavior of dlsym is to automatically prepend +an underscore to passed in symbol names, this allows easier porting of +applications which were written specifically for ELF based lifeforms. + +Installation +-------------- +Type: + ./configure + make + sudo make install + +This will compile the source file, generate both a static and shared +library called libdl and install it into /usr/local/lib.

This is a development snapshot! + +libffi-1.20 was released on October 5, 1998. Check the libffi web +page for updates: <URL:http://sources.redhat.com/libffi/>. + + +What is libffi? +=============== + +Compilers for high level languages generate code that follow certain +conventions. These conventions are necessary, in part, for separate +compilation to work. One such convention is the "calling +convention". The "calling convention" is essentially a set of +assumptions made by the compiler about where function arguments will +be found on entry to a function. A "calling convention" also specifies +where the return value for a function is found. + +Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call +a given function. Libffi can be used in such programs to provide a +bridge from the interpreter program to compiled code. + +The libffi library provides a portable, high level programming +interface to various calling conventions. This allows a programmer to +call any function specified by a call interface description at run +time. + +Ffi stands for Foreign Function Interface. A foreign function +interface is the popular name for the interface that allows code +written in one language to call code written in another language. The +libffi library really only provides the lowest, machine dependent +layer of a fully featured foreign function interface. A layer must +exist above libffi that handles type conversions for values passed +between the two languages. + + +Supported Platforms and Prerequisites +===================================== + +Libffi has been ported to: + + SunOS 4.1.3 & Solaris 2.x (SPARC-V8, SPARC-V9) + + Irix 5.3 & 6.2 (System V/o32 & n32) + + Intel x86 - Linux (System V ABI) + + Alpha - Linux and OSF/1 + + m68k - Linux (System V ABI) + + PowerPC - Linux (System V ABI, Darwin, AIX) + + ARM - Linux (System V ABI) + +Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are +that other versions will work. Libffi has also been built and tested +with the SGI compiler tools. + +On PowerPC, the tests failed (see the note below). + +You must use GNU make to build libffi. SGI's make will not work. +Sun's probably won't either. + +If you port libffi to another platform, please let me know! I assume +that some will be easy (x86 NetBSD), and others will be more difficult +(HP). + + +Installing libffi +================= + +[Note: before actually performing any of these installation steps, + you may wish to read the "Platform Specific Notes" below.] + +First you must configure the distribution for your particular +system. Go to the directory you wish to build libffi in and run the +"configure" program found in the root directory of the libffi source +distribution. + +You may want to tell configure where to install the libffi library and +header files. To do that, use the --prefix configure switch. Libffi +will install under /usr/local by default. + +If you want to enable extra run-time debugging checks use the the +--enable-debug configure switch. This is useful when your program dies +mysteriously while using libffi. + +Another useful configure switch is --enable-purify-safety. Using this +will add some extra code which will suppress certain warnings when you +are using Purify with libffi. Only use this switch when using +Purify, as it will slow down the library. + +Configure has many other options. Use "configure --help" to see them all. + +Once configure has finished, type "make". Note that you must be using +GNU make. SGI's make will not work. Sun's probably won't either. +You can ftp GNU make from prep.ai.mit.edu:/pub/gnu. + +To ensure that libffi is working as advertised, type "make test". + +To install the library and header files, type "make install". + + +Using libffi +============ + + The Basics + ---------- + +Libffi assumes that you have a pointer to the function you wish to +call and that you know the number and types of arguments to pass it, +as well as the return type of the function. + +The first thing you must do is create an ffi_cif object that matches +the signature of the function you wish to call. The cif in ffi_cif +stands for Call InterFace. To prepare a call interface object, use the +following function: + +ffi_status ffi_prep_cif(ffi_cif *cif, ffi_abi abi, + unsigned int nargs, + ffi_type *rtype, ffi_type **atypes); + + CIF is a pointer to the call interface object you wish + to initialize. + + ABI is an enum that specifies the calling convention + to use for the call. FFI_DEFAULT_ABI defaults + to the system's native calling convention. Other + ABI's may be used with care. They are system + specific. + + NARGS is the number of arguments this function accepts. + libffi does not yet support vararg functions. + + RTYPE is a pointer to an ffi_type structure that represents + the return type of the function. Ffi_type objects + describe the types of values. libffi provides + ffi_type objects for many of the native C types: + signed int, unsigned int, signed char, unsigned char, + etc. There is also a pointer ffi_type object and + a void ffi_type. Use &ffi_type_void for functions that + don't return values. + + ATYPES is a vector of ffi_type pointers. ARGS must be NARGS long. + If NARGS is 0, this is ignored. + + +ffi_prep_cif will return a status code that you are responsible +for checking. It will be one of the following: + + FFI_OK - All is good. + + FFI_BAD_TYPEDEF - One of the ffi_type objects that ffi_prep_cif + came across is bad. + + +Before making the call, the VALUES vector should be initialized +with pointers to the appropriate argument values. + +To call the the function using the initialized ffi_cif, use the +ffi_call function: + +void ffi_call(ffi_cif *cif, void *fn, void *rvalue, void **avalues); + + CIF is a pointer to the ffi_cif initialized specifically + for this function. + + FN is a pointer to the function you want to call. + + RVALUE is a pointer to a chunk of memory that is to hold the + result of the function call. Currently, it must be + at least one word in size (except for the n32 version + under Irix 6.x, which must be a pointer to an 8 byte + aligned value (a long long). It must also be at least + word aligned (depending on the return type, and the + system's alignment requirements). If RTYPE is + &ffi_type_void, this is ignored. If RVALUE is NULL, + the return value is discarded. + + AVALUES is a vector of void* that point to the memory locations + holding the argument values for a call. + If NARGS is 0, this is ignored. + + +If you are expecting a return value from FN it will have been stored +at RVALUE. + + + + An Example + ---------- + +Here is a trivial example that calls puts() a few times. + + #include <stdio.h> + #include <ffi.h> + + int main() + { + ffi_cif cif; + ffi_type *args[1]; + void *values[1]; + char *s; + int rc; + + /* Initialize the argument info vectors */ + args[0] = &ffi_type_uint; + values[0] = &s; + + /* Initialize the cif */ + if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ffi_type_uint, args) == FFI_OK) + { + s = "Hello World!"; + ffi_call(&cif, puts, &rc, values); + /* rc now holds the result of the call to puts */ + + /* values holds a pointer to the function's arg, so to + call puts() again all we need to do is change the + value of s */ + s = "This is cool!"; + ffi_call(&cif, puts, &rc, values); + } + + return 0; + } + + + + Aggregate Types + --------------- + +Although libffi has no special support for unions or bit-fields, it is +perfectly happy passing structures back and forth. You must first +describe the structure to libffi by creating a new ffi_type object +for it. Here is the definition of ffi_type: + + typedef struct _ffi_type + { + unsigned size; + short alignment; + short type; + struct _ffi_type **elements; + } ffi_type; + +All structures must have type set to FFI_TYPE_STRUCT. You may set +size and alignment to 0. These will be calculated and reset to the +appropriate values by ffi_prep_cif(). + +elements is a NULL terminated array of pointers to ffi_type objects +that describe the type of the structure elements. These may, in turn, +be structure elements. + +The following example initializes a ffi_type object representing the +tm struct from Linux's time.h: + + struct tm { + int tm_sec; + int tm_min; + int tm_hour; + int tm_mday; + int tm_mon; + int tm_year; + int tm_wday; + int tm_yday; + int tm_isdst; + /* Those are for future use. */ + long int __tm_gmtoff__; + __const char *__tm_zone__; + }; + + { + ffi_type tm_type; + ffi_type *tm_type_elements[12]; + int i; + + tm_type.size = tm_type.alignment = 0; + tm_type.elements = &tm_type_elements; + + for (i = 0; i < 9; i++) + tm_type_elements[i] = &ffi_type_sint; + + tm_type_elements[9] = &ffi_type_slong; + tm_type_elements[10] = &ffi_type_pointer; + tm_type_elements[11] = NULL; + + /* tm_type can now be used to represent tm argument types and + return types for ffi_prep_cif() */ + } + + + +Platform Specific Notes +======================= + + Intel x86 + --------- + +There are no known problems with the x86 port. + + Sun SPARC - SunOS 4.1.3 & Solaris 2.x + ------------------------------------- + +You must use GNU Make to build libffi on Sun platforms. + + MIPS - Irix 5.3 & 6.x + --------------------- + +Irix 6.2 and better supports three different calling conventions: o32, +n32 and n64. Currently, libffi only supports both o32 and n32 under +Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be +configured for whichever calling convention it was built for. + +By default, the configure script will try to build libffi with the GNU +development tools. To build libffi with the SGI development tools, set +the environment variable CC to either "cc -32" or "cc -n32" before +running configure under Irix 6.x (depending on whether you want an o32 +or n32 library), or just "cc" for Irix 5.3. + +With the n32 calling convention, when returning structures smaller +than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned. +Here's one way of forcing this: + + double struct_storage[2]; + my_small_struct *s = (my_small_struct *) struct_storage; + /* Use s for RVALUE */ + +If you don't do this you are liable to get spurious bus errors. + +"long long" values are not supported yet. + +You must use GNU Make to build libffi on SGI platforms. + + ARM - System V ABI + ------------------ + +The ARM port was performed on a NetWinder running ARM Linux ELF +(2.0.31) and gcc 2.8.1. + + + + PowerPC System V ABI + -------------------- + +There are two `System V ABI's which libffi implements for PowerPC. +They differ only in how small structures are returned from functions. + +In the FFI_SYSV version, structures that are 8 bytes or smaller are +returned in registers. This is what GCC does when it is configured +for solaris, and is what the System V ABI I have (dated September +1995) says. + +In the FFI_GCC_SYSV version, all structures are returned the same way: +by passing a pointer as the first argument to the function. This is +what GCC does when it is configured for linux or a generic sysv +target. + +EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a +inconsistency with the SysV ABI: When a procedure is called with many +floating-point arguments, some of them get put on the stack. They are +all supposed to be stored in double-precision format, even if they are +only single-precision, but EGCS stores single-precision arguments as +single-precision anyway. This causes one test to fail (the `many +arguments' test). + + +What's With The Crazy Comments? +=============================== + +You might notice a number of cryptic comments in the code, delimited +by /*@ and @*/. These are annotations read by the program LCLint, a +tool for statically checking C programs.

This is a development snapshot! + +libffi-1.20 was released on October 5, 1998. Check the libffi web +page for updates: <URL:http://sources.redhat.com/libffi/>. + + +What is libffi? +=============== + +Compilers for high level languages generate code that follow certain +conventions. These conventions are necessary, in part, for separate +compilation to work. One such convention is the "calling +convention". The "calling convention" is essentially a set of +assumptions made by the compiler about where function arguments will +be found on entry to a function. A "calling convention" also specifies +where the return value for a function is found. + +Some programs may not know at the time of compilation what arguments +are to be passed to a function. For instance, an interpreter may be +told at run-time about the number and types of arguments used to call +a given function. Libffi can be used in such programs to provide a +bridge from the interpreter program to compiled code. + +The libffi library provides a portable, high level programming +interface to various calling conventions. This allows a programmer to +call any function specified by a call interface description at run +time. + +Ffi stands for Foreign Function Interface. A foreign function +interface is the popular name for the interface that allows code +written in one language to call code written in another language. The +libffi library really only provides the lowest, machine dependent +layer of a fully featured foreign function interface. A layer must +exist above libffi that handles type conversions for values passed +between the two languages. + + +Supported Platforms and Prerequisites +===================================== + +Libffi has been ported to: + + SunOS 4.1.3 & Solaris 2.x (SPARC-V8, SPARC-V9) + + Irix 5.3 & 6.2 (System V/o32 & n32) + + Intel x86 - Linux (System V ABI) + + Alpha - Linux and OSF/1 + + m68k - Linux (System V ABI) + + PowerPC - Linux (System V ABI, Darwin, AIX) + + ARM - Linux (System V ABI) + +Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are +that other versions will work. Libffi has also been built and tested +with the SGI compiler tools. + +On PowerPC, the tests failed (see the note below). + +You must use GNU make to build libffi. SGI's make will not work. +Sun's probably won't either. + +If you port libffi to another platform, please let me know! I assume +that some will be easy (x86 NetBSD), and others will be more difficult +(HP). + + +Installing libffi +================= + +[Note: before actually performing any of these installation steps, + you may wish to read the "Platform Specific Notes" below.] + +First you must configure the distribution for your particular +system. Go to the directory you wish to build libffi in and run the +"configure" program found in the root directory of the libffi source +distribution. + +You may want to tell configure where to install the libffi library and +header files. To do that, use the --prefix configure switch. Libffi +will install under /usr/local by default. + +If you want to enable extra run-time debugging checks use the the +--enable-debug configure switch. This is useful when your program dies +mysteriously while using libffi. + +Another useful configure switch is --enable-purify-safety. Using this +will add some extra code which will suppress certain warnings when you +are using Purify with libffi. Only use this switch when using +Purify, as it will slow down the library. + +Configure has many other options. Use "configure --help" to see them all. + +Once configure has finished, type "make". Note that you must be using +GNU make. SGI's make will not work. Sun's probably won't either. +You can ftp GNU make from prep.ai.mit.edu:/pub/gnu. + +To ensure that libffi is working as advertised, type "make test". + +To install the library and header files, type "make install". + + +Using libffi +============ + + The Basics + ---------- + +Libffi assumes that you have a pointer to the function you wish to +call and that you know the number and types of arguments to pass it, +as well as the return type of the function. + +The first thing you must do is create an ffi_cif object that matches +the signature of the function you wish to call. The cif in ffi_cif +stands for Call InterFace. To prepare a call interface object, use the +following function: + +ffi_status ffi_prep_cif(ffi_cif *cif, ffi_abi abi, + unsigned int nargs, + ffi_type *rtype, ffi_type **atypes); + + CIF is a pointer to the call interface object you wish + to initialize. + + ABI is an enum that specifies the calling convention + to use for the call. FFI_DEFAULT_ABI defaults + to the system's native calling convention. Other + ABI's may be used with care. They are system + specific. + + NARGS is the number of arguments this function accepts. + libffi does not yet support vararg functions. + + RTYPE is a pointer to an ffi_type structure that represents + the return type of the function. Ffi_type objects + describe the types of values. libffi provides + ffi_type objects for many of the native C types: + signed int, unsigned int, signed char, unsigned char, + etc. There is also a pointer ffi_type object and + a void ffi_type. Use &ffi_type_void for functions that + don't return values. + + ATYPES is a vector of ffi_type pointers. ARGS must be NARGS long. + If NARGS is 0, this is ignored. + + +ffi_prep_cif will return a status code that you are responsible +for checking. It will be one of the following: + + FFI_OK - All is good. + + FFI_BAD_TYPEDEF - One of the ffi_type objects that ffi_prep_cif + came across is bad. + + +Before making the call, the VALUES vector should be initialized +with pointers to the appropriate argument values. + +To call the the function using the initialized ffi_cif, use the +ffi_call function: + +void ffi_call(ffi_cif *cif, void *fn, void *rvalue, void **avalues); + + CIF is a pointer to the ffi_cif initialized specifically + for this function. + + FN is a pointer to the function you want to call. + + RVALUE is a pointer to a chunk of memory that is to hold the + result of the function call. Currently, it must be + at least one word in size (except for the n32 version + under Irix 6.x, which must be a pointer to an 8 byte + aligned value (a long long). It must also be at least + word aligned (depending on the return type, and the + system's alignment requirements). If RTYPE is + &ffi_type_void, this is ignored. If RVALUE is NULL, + the return value is discarded. + + AVALUES is a vector of void* that point to the memory locations + holding the argument values for a call. + If NARGS is 0, this is ignored. + + +If you are expecting a return value from FN it will have been stored +at RVALUE. + + + + An Example + ---------- + +Here is a trivial example that calls puts() a few times. + + #include <stdio.h> + #include <ffi.h> + + int main() + { + ffi_cif cif; + ffi_type *args[1]; + void *values[1]; + char *s; + int rc; + + /* Initialize the argument info vectors */ + args[0] = &ffi_type_uint; + values[0] = &s; + + /* Initialize the cif */ + if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, + &ffi_type_uint, args) == FFI_OK) + { + s = "Hello World!"; + ffi_call(&cif, puts, &rc, values); + /* rc now holds the result of the call to puts */ + + /* values holds a pointer to the function's arg, so to + call puts() again all we need to do is change the + value of s */ + s = "This is cool!"; + ffi_call(&cif, puts, &rc, values); + } + + return 0; + } + + + + Aggregate Types + --------------- + +Although libffi has no special support for unions or bit-fields, it is +perfectly happy passing structures back and forth. You must first +describe the structure to libffi by creating a new ffi_type object +for it. Here is the definition of ffi_type: + + typedef struct _ffi_type + { + unsigned size; + short alignment; + short type; + struct _ffi_type **elements; + } ffi_type; + +All structures must have type set to FFI_TYPE_STRUCT. You may set +size and alignment to 0. These will be calculated and reset to the +appropriate values by ffi_prep_cif(). + +elements is a NULL terminated array of pointers to ffi_type objects +that describe the type of the structure elements. These may, in turn, +be structure elements. + +The following example initializes a ffi_type object representing the +tm struct from Linux's time.h: + + struct tm { + int tm_sec; + int tm_min; + int tm_hour; + int tm_mday; + int tm_mon; + int tm_year; + int tm_wday; + int tm_yday; + int tm_isdst; + /* Those are for future use. */ + long int __tm_gmtoff__; + __const char *__tm_zone__; + }; + + { + ffi_type tm_type; + ffi_type *tm_type_elements[12]; + int i; + + tm_type.size = tm_type.alignment = 0; + tm_type.elements = &tm_type_elements; + + for (i = 0; i < 9; i++) + tm_type_elements[i] = &ffi_type_sint; + + tm_type_elements[9] = &ffi_type_slong; + tm_type_elements[10] = &ffi_type_pointer; + tm_type_elements[11] = NULL; + + /* tm_type can now be used to represent tm argument types and + return types for ffi_prep_cif() */ + } + + + +Platform Specific Notes +======================= + + Intel x86 + --------- + +There are no known problems with the x86 port. + + Sun SPARC - SunOS 4.1.3 & Solaris 2.x + ------------------------------------- + +You must use GNU Make to build libffi on Sun platforms. + + MIPS - Irix 5.3 & 6.x + --------------------- + +Irix 6.2 and better supports three different calling conventions: o32, +n32 and n64. Currently, libffi only supports both o32 and n32 under +Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be +configured for whichever calling convention it was built for. + +By default, the configure script will try to build libffi with the GNU +development tools. To build libffi with the SGI development tools, set +the environment variable CC to either "cc -32" or "cc -n32" before +running configure under Irix 6.x (depending on whether you want an o32 +or n32 library), or just "cc" for Irix 5.3. + +With the n32 calling convention, when returning structures smaller +than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned. +Here's one way of forcing this: + + double struct_storage[2]; + my_small_struct *s = (my_small_struct *) struct_storage; + /* Use s for RVALUE */ + +If you don't do this you are liable to get spurious bus errors. + +"long long" values are not supported yet. + +You must use GNU Make to build libffi on SGI platforms. + + ARM - System V ABI + ------------------ + +The ARM port was performed on a NetWinder running ARM Linux ELF +(2.0.31) and gcc 2.8.1. + + + + PowerPC System V ABI + -------------------- + +There are two `System V ABI's which libffi implements for PowerPC. +They differ only in how small structures are returned from functions. + +In the FFI_SYSV version, structures that are 8 bytes or smaller are +returned in registers. This is what GCC does when it is configured +for solaris, and is what the System V ABI I have (dated September +1995) says. + +In the FFI_GCC_SYSV version, all structures are returned the same way: +by passing a pointer as the first argument to the function. This is +what GCC does when it is configured for linux or a generic sysv +target. + +EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a +inconsistency with the SysV ABI: When a procedure is called with many +floating-point arguments, some of them get put on the stack. They are +all supposed to be stored in double-precision format, even if they are +only single-precision, but EGCS stores single-precision arguments as +single-precision anyway. This causes one test to fail (the `many +arguments' test). + + +What's With The Crazy Comments? +=============================== + +You might notice a number of cryptic comments in the code, delimited +by /*@ and @*/. These are annotations read by the program LCLint, a +tool for statically checking C programs.
