>>Can C functions be used issuing DECLARE in MSVCRT.DLL VFP as API ones are used? > >Sure you can, just as you listed above, and just like you would call a Win32 API function. There's plenty of fun stuff in the C runtime that you may not find anywhere else. For instance, there's _fpreset(), which is used to fix a bug in many printer drivers. I used that function in the article because, hey, guess what, there's no other way to reset the FPU (at least none that I found).
Yep; most C-style DLL functions which don't use callbacks can be called from VFP; some may need to use an add-on such as Christof Lange's STRUCT or my CLSHEAP to handle pointer and structure-related issues.
