c++ - Need chars to void function its address? -

-

need specify address of char array opcodes (&opcodes)? i'm casting void pointer, see indeed specify again address (fp points address opcodes -> points opcodes).

char opcodes[] = "\x41\x41...";  void main() {     void(*fp) (void);     fp = (void *)&opcodes; // opcodes or &opcodes     fp(); }

perhaps.

the c standard nor c++ standard have answer this. both of them, it's undefined behavior. might vary implementation implementation, if it's possible.

if give specific compiler, might able answer it.
