NAME

memfrob - frobnicate (encrypt) a memory area  

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 suitable only for hiding strings.  

RETURN VALUE

The memfrob() function returns a pointer to the encrypted memory area.  

ATTRIBUTES

The memfrob() function is thread-safe.  

CONFORMING TO
