+  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...

+instance methods/properties
+---------------------------
+
+_as_parameter_
+       - convert self into a C function call parameter

+  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

+ StgDictObject fields

+ corresponding fielddesc entry.  These are functions to set and get the value
+ in a memory block.
+ 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>.

+   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:

+   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

+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;

+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:
