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 hid-
     ing 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.
