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 hiding strings.
The memfrob() function returns a pointer to the encrypted memory
The memfrob() function is unique to the
GNU C Library.
