User:Memfrob
memfrob − frobnicate (encrypt) a memory area
SYNOPSIS
[edit]#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <string.h>
void *memfrob(void *s, size_t n);
DESCRIPTION
[edit]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 suitable only for hiding strings.
RETURN VALUE
[edit]The memfrob() function returns a pointer to the encrypted memory area.
