Abdulaziz Ghuloum 7e965758cf Added memcpy (courtesy of Andreas Rottmann). 
The `memcpy' procedure allows to copy memory from bytevectors to
  unmanaged (malloc'ed) memory and vice-versa.

Abdulaziz Ghuloum 2f4a2f3895 The code for converting signed long long numbers to scheme bignums 
was broken (on 32-bits, the 64-bit value was put in a bignum of 1
limb instead of 2).  Thanks to Andreas Rottmann for reporting it.

Abdulaziz Ghuloum 6bab4af5b4 Added [un]signed-long-long types as valid parameter types to 
callouts and callbacks (in both 32 and 64 bit modes). (UNTESTED)

Abdulaziz Ghuloum d35f039ca1 ikrt_last_errno moved to ikarus-runtime where it belongs 2008-11-26 05:03:16 -05:00
Abdulaziz Ghuloum 6922b0d9c2 added pointer-ref-{unsigned-,}long-long 2008-11-21 05:56:51 -05:00
Abdulaziz Ghuloum 25f40fefb0 Added the following file system primitives 
- file-readable? path -> boolean
 - file-writable? path -> boolean
 - file-executable? path -> boolean
 - file-size path -> integer
 - rename-file source dest -> void
(thanks to Andreas Rottmann)

Abdulaziz Ghuloum 69c62649cc - defined RTLD_LOCAL for cygwin (possibly incorrect) 
- added a missing save to a callee-save register (%edi) 
  when entering/reentering to Scheme which caused Ikarus
  not to run properly depending on whether or not gcc places
  the pcb in %edi or not during Scheme execution.
- updated lab/test-ffi.ss to use the new names for foreign
  types, etc.

Abdulaziz Ghuloum 1e5e516b08 - added (ikarus foreign) library that should be used instead of 
(ikarus system $foreign).
- changed the names of some of the pointer primitives
- changed the name of the procedure make-ffi to make-callout
- updated examples and libraries to conform with new names
- updated the users guide to provide a complete description of 
  the (ikarus foreign) library
- updated list of missing R6RS features in the users guide

Abdulaziz Ghuloum 61ecbe0dd1 - opengl demos from ypsilon (gears and glut-demo) now work under 
ikarus's ffi using a compatibility layer.

Abdulaziz Ghuloum 31f5f88889 first test of ffi works: 
> (import (ikarus system $foreign))
> (((ffi-prep-cif 'void '(uint32))
    (dlsym (dlopen #f) "hello_world"))

Abdulaziz Ghuloum 8e750562d6 - Added memory operations on pointer types for setting and accessing
