FREE(3)                     BSD 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'').
