Peter,

If the C code is not trying to access VFP routines then it's much simpler to just compile the C code to a DLL and use a DECLARE command in VFP to access it. There are two different VC++ sample projects and the VFP code to access the DLLs over on my website. They are under the Samples section SpyIn and DeQuote.
