Your suspicion is right. You want to write a C function like this


void call_function(char *argtypes, void (*fptr)(), ...)
{
    /* use information in argtypes to call fptr with arguments */
}


Unfortunately it can't be done in ANSI C. It's not too difficult to do
in assembly language however, as long as you know the calling
convention.
