• Failure: A null pointer is returned.

Example

#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>

#define KQMALLOC_TEST_LEN 10

void CallocExample()
{
    int8_t *res = (int8_t *)calloc(KQMALLOC_TEST_LEN, KQMALLOC_TEST_LEN);
    if (res == NULL) {
        printf("res is null\n");
    } else {
        printf("calloc pointer address: %lx\n", res);
        free(res);
    }
}

int main(void) {
    CallocExample();
    return 0;
}

Output:
