FREE(3) MachTen Programmer’s Manual FREE(3)

NAME
free - free up memory allocated with malloc, calloc or realloc

SYNOPSIS
#include <stdlib.h>

void
free(void *ptr)

DESCRIPTION
The free() function causes the space pointed to by ptr to be deallocated,
that is, made available for further allocation. If ptr is a null point-
er, no action occurs. Otherwise, if the argument does not match a point-
er earlier returned by the calloc, malloc, or realloc function, or if
the space has been deallocated by a call to free() or realloc, general
havoc may occur.

RETURN VALUES
The free() function returns no value.

SEE ALSO
calloc(3), malloc(3), realloc(3)

STANDARDS
The free() function conforms to ANSI C3.159-1989 (‘‘ANSI C’’).
