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.
