NAME
       memfrob - frobnicate (encrypt) a memory area

SYNOPSIS
       #define _GNU_SOURCE
       #include <string.h>

       void *memfrob(void *s, size_t n);

DESCRIPTION
       The  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 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.

RETURN VALUE
       The memfrob() function returns a pointer to the encrypted memory area.

CONFORMING TO
       The memfrob() function is unique to the GNU C Library.
