Re: StdCall and pragma Import_Function

typedef signed __int32 cl_int;

typedef struct _cl_platform_id *  cl_platform_id;

typedef unsigned __int64 cl_ulong;
typedef cl_ulong cl_bitfield;
typedef cl_bitfield cl_device_type;

typedef struct _cl_device_id * cl_device_id;

typedef unsigned __int32  cl_uint;

(For further details, the headers are available at http://www.khronos.org/registry/cl/ as cl.h and cl_platform.h)

As this problem definitely is fixable (by substituting the bit vector types with ULong in the function definitions), I'm confident I'll get my bindings working cross-platform. Unlike Glib, OpenCL is an open standard and there was much effort to make the API as clear and portable as possible. There also exist cross-platform bindings for the related OpenGL API in Ada, so it definitely is possible.
