void *calloc(size_t nelem, size_t elsize);

Why the test for calloc limit is passing pointer difference limit as an
argument? The limit is defined as SIZE_MAX in C99 standard.

#include <stdlib.h>
#include <limits.h>
#include <stdio.h>
#include <errno.h>
#include <string.h>

void main(){
        void * a = calloc(SIZE_MAX, 1);
        printf("a: %p, errno: %d, strerror: %s\n", a, errno, strerror(errno));
}
