10
11       void *memfrob(void *s, size_t n);

DESCRIPTION

14       The  memfrob() function encrypts the first n bytes of the memory area s
15       by exclusive-ORing each character with the number 42.  The  effect  can
16       be reversed by using memfrob() on the encrypted memory area.
17
18       Note  that  this function is not a proper encryption routine as the XOR
19       constant is fixed, and is only suitable for hiding strings.
20

RETURN VALUE

22       The memfrob() function returns a pointer to the encrypted memory area.
23

CONFORMING TO

25       The memfrob() function is unique to the GNU C Library.
