Synopsis
Description

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.
