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.
