free_b

#include <stdlib.h>

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

or

void free_b (
  void huge *p);     /* block to free */

The free_b function returns a memory block to the memory pool. The p argument points to a memory block that was previously allocated with the calloc_b, malloc_b, or realloc_b functions. Once it has been returned to the memory pool by the free_b function, the block is available for subsequent allocation.

If p is a null pointer, it is ignored.
