How to format a function pointer?
- by Longpoke
Is there any way to print a pointer to a function in ANSI C? Of course this means you have to cast the function pointer to void pointer, but it appears that's not possible??
#include <stdio.h>
int main() {
int (*funcptr)() = main;
printf("%p\n", (void* )funcptr);
printf("%p\n", (void* )main);
return 0;
}
$ gcc -ansi -pedantic -Wall test.c -o
test test.c: In function
'main': test.c:6: warning: ISO C
forbids conversion of function pointer
to object pointer type test.c:7:
warning: ISO C forbids conversion of
function pointer to object pointer
type $ ./test 0x400518
0x400518
It's "working", but non-standard...
