wow, thanks a lot for this answer. But one annotation:

Please, please please make this CS_GetFunctionInfo public (export symbols to acknex.dll).
This function would really really help a lot (e.g. getting stacksize of a single function, or the parametersize).

I do not need entries in afuns.h (or similar), just an export, so i can retrieve the address via GetProcAddress.

This would probably allow to implement a "real" profiler.
