FREE(3) BSD Library Functions Manual FREE(3)NAMEfree — 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
pointer, no action occurs. Otherwise, if the argument does not match a
pointer 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.
