For the record, memcpy returns a pointer basically as a convenience of
notation. It is often nice to pass the return of memcpy straight on to
something else in the same line. For instance:

        char *a, *b;
        ...
        memcpy (b, a, sizeof char);
        dosomethingelse (b);
// as opposed to...
        dosomethingelse( memcpy(b, a, sizeof char));

(Man! C++ has made my C skills rot... That seems soo complicated... :)
