FREE

The FREE macro is a platform-independent substitute for the C library routine free. This macro deallocates the space previously allocated by MALLOC, CALLOC, or STRDUP from the request’s memory pool.

Syntax

FREE(void *ptr);

Returns

void

Parameters

void *ptr is a (void *) pointer to a block of memory. If the pointer was not created by MALLOC, CALLOC, or STRDUP, the behavior is undefined.

Example

char *name;name = (char *) MALLOC(256);...FREE(name);
