Status
|
|
||||||
======
|
|
||||||
|
|
||||||
libffi-2.00 has not been released yet! 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. */

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. You can read all about it at
|
|
||||||
<http://larch-www.lcs.mit.edu:8001/larch/lclint/index.html>.

Authors & Credits
|
|
||||||
=================
|
|
||||||
|
|
||||||
libffi was written by Anthony Green <green@cygnus.com>.
|
|
||||||
|
|
||||||
Portions of libffi were derived from Gianni Mariani's free gencall
|
|
||||||
library for Silicon Graphics machines.
|
|
||||||
|
|
||||||
The closure mechanism was designed and implemented by Kresten Krab
|
|
||||||
Thorup.
|
|
||||||
|
|
||||||
The Sparc port was derived from code contributed by the fine folks at
|
|
||||||
Visible Decisions Inc <http://www.vdi.com>. Further enhancements were
|
|
||||||
made by Gordon Irlam at Cygnus Solutions <http://www.cygnus.com>.
|
|
||||||
|
|
||||||
The Alpha port was written by Richard Henderson at Cygnus Solutions.
|
|
||||||
|
|
||||||
Andreas Schwab ported libffi to m68k Linux and provided a number of
|
|
||||||
bug fixes.
|
|
||||||
|
|
||||||
Geoffrey Keating ported libffi to the PowerPC.
|
|
||||||
|
|
||||||
Raffaele Sena ported libffi to the ARM.
|
|
||||||
|
|
||||||
Jesper Skov and Andrew Haley both did more than their fair share of
|
|
||||||
stepping through the code and tracking down bugs.
|
|
||||||
|
|
||||||
Thanks also to Tom Tromey for bug fixes and configuration help.
|
|
||||||
|
|
||||||
Thanks to Jim Blandy, who provided some useful feedback on the libffi
|
|
||||||
interface.
|
|
||||||

|

The purpose is to hack the libffi sources so that they can be compiled
|
|
||||||
with MSVC, and to extend them so that they have the features I need
|
|
||||||
for ctypes.
|
|
||||||
|
|
||||||
I retrieved the libffi sources from the gcc cvs repository on
|
|
||||||
2004-01-27. Then I did 'configure' in a 'build' subdirectory on a x86
|
|
||||||
linux system, and copied the files I found useful.
