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.
