Синопсис (Synopsis)

void *memfrob(void *s, size_t n);
Описание (Description)
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 suitable only for hiding strings.
Возвращаемое значение (Return value)
The memfrob() function returns a pointer to the encrypted memory
area.
