Is there a standard way to print an address of a function?

Question

You may think of this:

#include <stdio.h>
int main(void)
{
        printf("%p\n", main);
        return 0;
}

However, with gcc -std=c11 -pedantic you get:

warning: format '%p' expects argument of type void *, but argument 2 has type int (*)(void) [-Wformat=]

Then you may think of this:

#include <stdio.h>
int main(void)
{
        printf("%p\n", (void*)main);
        return 0;
}

However, with gcc -std=c11 -pedantic you get:

warning: ISO C forbids conversion of function pointer to object pointer type [-Wpedantic]
