FREE(3P) POSIX Programmer's Manual FREE(3P)PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
free - free allocated memory
SYNOPSIS
#include <stdlib.h>
void free(void *ptr);
DESCRIPTION
The free() function shall cause the space pointed to by ptr to be deallocated; that is, made available for further allocation. If ptr is a
null pointer, no action shall occur. Otherwise, if the argument does not match a pointer earlier returned by the calloc(), malloc(),
posix_memalign(), realloc(), or strdup() function, or if the space has been deallocated by a call to free() or realloc(), the behavior
is undefined.
Any use of a pointer that refers to freed space results in undefined behavior.
RETURN VALUE
The free() function shall not return a value.
ERRORS
No errors are defined.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
There is now no requirement for the implementation to support the inclusion of <malloc.h>.
RATIONALE
None.
FUTURE DIRECTIONS
None.
