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

NAME
       memfrob - frobnicate (encrypt) a memory area

SYNOPSIS
       #define _GNU_SOURCE             /* See feature_test_macros(7) */
       #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.

I thought this was a joke!  But it's real.

What a joke of a C library, and by extension of a joke of an operating system what would use such a C library.
