PERM_FREE

The PERM_FREE macro is a platform-independent substitute for the C library routine free. It deallocates the persistent space previously allocated by PERM_MALLOC, PERM_CALLOC, or PERM_STRDUP. If pooled memory has been disabled in the configuration file (with the pool-init built-in SAF), both PERM_FREE and FREE deallocates memory in the system heap.

Syntax

PERM_FREE(void *ptr);

Returns

void

Parameters

void *ptr is a (void *) pointer to block of memory. If the pointer is not one created by PERM_MALLOC, PERM_CALLOC, or PERM_STRDUP, the behavior is undefined.

Example

char *name;name = (char *) PERM_MALLOC(256);...PERM_FREE(name);
