xmalloc

#include <stdlib.h>

void xhuge *xmalloc (
  unsigned long size);      /* block size to allocate */

The xmalloc function allocates a memory block from the memory pool of size bytes in length.

Note

The xmalloc function returns a pointer to the allocated block or a null pointer if there is not enough memory to satisfy the allocation request.

  p = xmalloc (1000); /* allocate 1000 bytes */

  if (p == NULL)
    printf ("Not enough memory space\n");
  else
    printf ("Memory allocated\n");
