Should you dereference function pointers?

Name: Anonymous 2009-11-04 19:33

#include <stdio.h>

void func() {
  printf("hello world\n");
}

void (*go)() = func;

int main() {
  go();    // number 1...
  (*go)(); // or number 2
  return 0;
}


Which is correct ANSI C89? GCC accepts both, even in -ansi -pedantic; it outputs hello world twice.

Oh, also, should you take the address of the function or no?


void (*a)() = func;
void (*b)() = &func;
