NAMEmemfrob - frobnicate (encrypt) a memory area
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include
void *memfrob(void * s , size_t n );
DESCRIPTIONThe 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 VALUEThe memfrob() function returns a pointer to the encrypted memory area.
CONFORMING TOThe memfrob() function is unique to the GNU C Library.
