NAME
       memfrob - frobnicate (encrypt) a memory area

SYNOPSIS
       #define _GNU_SOURCE
       #include 

       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.
