memfrob - frobnicate (encrypt) a memory area
void *memfrob(void *s, size_t n);
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 hid-
The memfrob() function returns a pointer to the encrypted
The memfrob() function is unique to the Linux C Library and
GNU C Library.
