No... a function pointer isn't a data pointers (and there are several architectures which reflect this). It's also a potential source of security weaknesses. Is the function prototype variable? Or cast it through a typedef void (void_fn*)(void); void_fn fnp; variable, which at least retains the 'functionness' of the pointer.
