memfrob - frobnicate (encrypt) a memory area
SYNOPSIS
#include <string.h>
I void *memfrob(void * s , size_t n );
DESCRIPTION
The
R memfrob ()
function encrypts the first n bytes of the
memory area s by exclusive-ORing each character with the number
42.
The effect can be reversed by using
R memfrob ()
on the
encrypted memory area.
Note that this function is not a proper encryption routine as the XOR
constant is fixed, and is only suitable for hiding strings.

function returns a pointer to the encrypted memory
area.

R memfrob ()
function is unique to the
GNU C Library.
