Well, if you have a set of C functions, their header file can contain 
something like this to avoid C++ mangling the function names.

#ifdef __cplusplus
extern "C" {
#endif

void hsort( void *base, size_t nelem, size_t width, int (*fcmp)(const void *, 
const void *) );
void bsort( void *base, size_t nelem, size_t width, int (*fcmp)(const void *, 
const void *) );

#ifdef __cplusplus
}
#endif


Kind regards,
