xfree

#include <stdlib.h>

void xfree (
  void xhuge *p);      /* block to free */

The xfree function returns a memory block to the memory pool. The p argument points to a memory block that was previously allocated with the xcalloc, xmalloc, or xrealloc functions. Once it has been returned to the memory pool by the free function, the block is available for subsequent allocation.

If p is a null pointer, it is ignored.

Note

None.

  mbuf = xmalloc (1000);

  if (mbuf == NULL) {
    printf ("Unable to allocate memory\n");
  }

  else {
    xfree (mbuf);
    printf ("Memory free\n");
