MEMFROB(3)          Linux Programmer's Manual          MEMFROB(3)

NAME
       memfrob - frobnicate (encrypt) a memory area

SYNOPSIS
       #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 Linux C Library
       and GNU C Library.
