ffree

#include <stdlib.h>

void ffree (
  void far *p);      /* block to free */

The ffree function returns a memory block to the memory pool. The p argument points to a memory block that was previously allocated with the fcalloc, fmalloc, or frealloc 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.
