User:Memfrob

From Wikipedia, the free encyclopedia

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.
