fcalloc

#include <stdlib.h>

void far *fcalloc (
  unsigned long num,           /* number of items */
  unsigned long len);          /* length of each item */

The fcalloc function allocates memory for an array of numelements. Each element in the array occupies len bytes and is initialized to 0. The total number of bytes of memory allocated is num * len.

Note

• Source code for this routine is provide in the LIB folder. You may modify the source to customize this function for your particular hardware environment.

The fcalloc function returns a pointer to the allocated memory or a null pointer if the memory allocation request cannot be satisfied.

#include <stdlib.h>
#include <stdio.h> /* for printf */

void tst_calloc (void) {
  int far *p; /* ptr to array of 100 ints */

  p = xcalloc (100, sizeof (int));

  if (p == NULL)
    printf ("Error allocating array\n");
  else
    printf ("Array address is %p\n", (void *) p);
}
