+ ToDo:
+
+ Get rid of the checker (and also the converters) field in CFuncPtrObject and
+ StgDictObject, and replace them by slot functions in StgDictObject.
+
+ think about a buffer-like object (memory? bytes?)
+
+ Should POINTER(c_char) and POINTER(c_wchar) have a .value property?
+ What about c_char and c_wchar arrays then?
+
+ Add from_mmap, from_file, from_string metaclass methods.
+
+ Maybe we can get away with from_file (calls read) and with a from_buffer
+ method?
+
+ And what about the to_mmap, to_file, to_str(?) methods? They would clobber
+ the namespace, probably. So, functions instead? And we already have memmove...

+
+It has some similarity to the byref() construct compared to pointer()
+from_address(addr)
+ - construct an instance from a given memory block (sharing this memory block)
+
+from_param(obj)
+ - typecheck and convert a Python object into a C function call parameter
+ the result may be an instance of the type, or an integer or tuple
+ (typecode, value[, obj])
+
+instance methods/properties
+---------------------------
+
+_as_parameter_
+ - convert self into a C function call parameter
+ This is either an integer, or a 3-tuple (typecode, value, obj)
+
+functions
+---------
+
+sizeof(cdata)
+ - return the number of bytes the buffer contains
+
+sizeof(ctype)
+ - return the number of bytes the buffer of an instance would contain
+
+byref(cdata)
+
+addressof(cdata)
+
+pointer(cdata)
+
+POINTER(ctype)
+
+bytes(cdata)
+ - return the buffer contents as a sequence of bytes (which is currently a string)

+ How are functions called, and how are parameters converted to C ?
+
+ 1. _ctypes.c::CFuncPtr_call receives an argument tuple 'inargs' and a
+ keyword dictionary 'kwds'.
+
+ 2. After several checks, _build_callargs() is called which returns another
+ tuple 'callargs'. This may be the same tuple as 'inargs', a slice of
+ 'inargs', or a completely fresh tuple, depending on several things (is is a
+ COM method, are 'paramflags' available).
+
+ 3. _build_callargs also calculates bitarrays containing indexes into
+ the callargs tuple, specifying how to build the return value(s) of
+ the function.
+
+ 4. _CallProc is then called with the 'callargs' tuple. _CallProc first
+ allocates two arrays. The first is an array of 'struct argument' items, the
+ second array has 'void *' entried.
+
+ 5. If 'converters' are present (converters is a sequence of argtypes'
+ from_param methods), for each item in 'callargs' converter is called and the
+ result passed to ConvParam. If 'converters' are not present, each argument
+ is directly passed to ConvParm.
+
+ 6. 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. The 'void *' argument array is what _call_function_pointer
+ expects. _call_function_pointer then has very little to do - only some
+ libffi specific stuff, then it calls ffi_call.
+
+ So, there are 4 data structures holding processed arguments:
+ - the inargs tuple (in CFuncPtr_call)
+ - the callargs tuple (in CFuncPtr_call)
+ - the 'struct argguments' array
+ - the 'void *' array

+ They should probably by used by other types as well.
+
+ proto is only used for Pointer and Array types - it points to the item type
+ object.
+
+ Probably all the magic ctypes methods (like from_param) should have C
+ callable wrappers in the StgDictObject. For simple data type, for example,
+ the fielddesc table could have entries for C codec from_param functions or
+ other methods as well, if a subtype overrides this method in Python at
+ construction time, or assigns to it later, tp_setattro should update the
+ StgDictObject function to a generic one.
+
+ Currently, CFuncPtr types have 'converters' and 'checker' entries in their
+ type dict. They are only used to cache attributes from other entries, whihc
+ is wrong.
+
+ One use case is the .value attribute that all simple types have. But some
+ complex structures, like VARIANT, represent a single value also, and should
+ have this attribute.
+
+ Another use case is a _check_retval_ function, which is called when a ctypes
+ type is used as return type of a function to validate and compute the return
+ value.
+
+ Common ctypes protocol:
+
+ - setfunc: store a python value in a memory block
+ - getfunc: convert data from a memory block into a python value
+
+ - checkfunc: validate and convert a return value from a function call
+ - toparamfunc: convert a python value into a function argument

+dlcompat for Darwin
+=========================
+
+This is dlcompat, a small library that emulates the dlopen()
+interface on top of Darwin's dyld API.
+
+dlcompat allows loading a ".dylib" library (as long as the RTLD_LOCAL
+flag isn't passed to dlopen()). 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. The header
+file dlfcn.h will be installed in /usr/local/include.
+
+If you want to place the files somewhere else, run
+
+ make clean
+ ./configure --prefix=<prefix>
+ make
+ sudo make install
+
+where <prefix> is the hierarchy you want to install into, e.g. /usr
+for /usr/lib and /usr/include (_NOT_ recommended!).
+
+To enable debugging output (useful for me), run
+
+ make clean
+ ./configure --enable-debug
+ make
+ sudo make install
+
+If you want old dlcompat style behavior of not prepending the underscore
+on calls to dlsym then type:
+
+ make clean
+ ./configure --enable-fink
+ make
+ sudo make install
+
+Usage
+-------
+Software that uses GNU autoconf will likely check for a library called
+libdl, that's why I named it that way. For software that doesn't find
+the library on its own, you must add a '-ldl' to the appropriate
+Makefile (or environment) variable, usually LIBS.
+
+If you installed dlcompat into a directory other than /usr/local/lib,
+you must tell the compiler where to find it. Add '-L<prefix>/lib' to
+LDFLAGS (or CFLAGS) and '-I<prefix>/include' to CPPFLAGS (or CFLAGS).
+
+Notes
+-----
+If you are writing new software and plan to have Mac OX X compatibility you
+should look at the dyld api's in /usr/include/mach-o/dyld.h, rather than
+using dlcompat, using the native api's is the supported method of loading
+dynamically on Mac OS X, if you want an small example, look at dlfcn_simple.c,
+which should help get you started.
+
+Also note that the functions in dlcompat are not thread safe, and while it is not
+POSIX spec compliant, it is about as close to compliance as it is going to get though.
+
+You can always get the latest version from opendarwin cvs:
+
+ cvs -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od login
+ cvs -z3 -d :pserver:anonymous@anoncvs.opendarwin.org:/cvs/od \
+ co -d dlcompat proj/dlcompat
+
+
+It is hoped that this library will be useful, and as bug free as possible, if you find
+any bugs please let us know about them so they can be fixed.
+
+Please send bug reports to Peter O'Gorman <ogorman@users.sourceforge.net>
+
+Thanks.

+This directory contains the libffi package, which is not part of GCC but
+shipped with GCC as convenience.
+
+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. */
+ 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. 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.
+
+If you have a problem, or have found a bug, please send a note to

+ The basic API is described in the README file.
+
+ The raw API is designed to bypass some of the argument packing
+ and unpacking on architectures for which it can be avoided.
+
+ The closure API allows interpreted functions to be packaged up
+ inside a C function pointer, so that they can be called as C functions,
+ with no understanding on the client side that they are interpreted.
+ It can also be used in other cases in which it is necessary to package
+ up a user specified parameter and a function pointer as a single
+ function pointer.
+
+ The closure API must be implemented in order to get its functionality,
+ e.g. for use by gij. Routines are provided to emulate the raw API
+ if the underlying platform doesn't allow faster implementation.
+
+ More details on the raw and cloure API can be found in:
+
+ http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+ and
+

+ The basic API is described in the README file.
+
+ The raw API is designed to bypass some of the argument packing
+ and unpacking on architectures for which it can be avoided.
+
+ The closure API allows interpreted functions to be packaged up
+ inside a C function pointer, so that they can be called as C functions,
+ with no understanding on the client side that they are interpreted.
+ It can also be used in other cases in which it is necessary to package
+ up a user specified parameter and a function pointer as a single
+ function pointer.
+
+ The closure API must be implemented in order to get its functionality,
+ e.g. for use by gij. Routines are provided to emulate the raw API
+ if the underlying platform doesn't allow faster implementation.
+
+ More details on the raw and cloure API can be found in:
+
+ http://gcc.gnu.org/ml/java/1999-q3/msg00138.html
+
+ and
+
+ http://gcc.gnu.org/ml/java/1999-q3/msg00174.html

+This directory contains the libffi package, which is not part of GCC but
+shipped with GCC as convenience.
+
+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. */
+ 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. 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.
+
+If you have a problem, or have found a bug, please send a note to
+green@cygnus.com.

+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.

+ The basic API is described in the README file.
+
+ The raw API is designed to bypass some of the argument packing
+ and unpacking on architectures for which it can be avoided.
+
+ The closure API allows interpreted functions to be packaged up
+ inside a C function pointer, so that they can be called as C functions,
+ with no understanding on the client side that they are interpreted.
+ It can also be used in other cases in which it is necessary to package
+ up a user specified parameter and a function pointer as a single
+ function pointer.
+
+ The closure API must be implemented in order to get its functionality,
+ e.g. for use by gij. Routines are provided to emulate the raw API
+ if the underlying platform doesn't allow faster implementation.
+
+ More details on the raw and cloure API can be found in:
