FREE(P)			   POSIX Programmer's Manual		       FREE(P)

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 deal‐
       located; 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.
