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.
