xfree

Syntax

#include <stdlib.h> void xfree(void *ptr);

Description

Frees memory allocated by xmalloc (see section xmalloc). This function guarantees that a NULL pointer is handled gracefully.

Note that, currently, the header `stdlib.h' does not declare a prototype for xfree, because many programs declare its prototype in different and conflicting ways. If you use xfree in your own code, you might need to provide your own prototype explicitly.

Portability

ANSI/ISO C	No
POSIX	No

Example

void *f = xmalloc(100); xfree(f);
