Actually, the IEEE Std 1003.1-2001 spec. for <sys/socket.h> states:

    "Inclusion of <sys/socket.h> may also make visible all symbols
    from <sys/uio.h>."

So, it seems it would be sufficient to have a single definition of
struct iovec in <sys/uio.h>.

It would seem to also work having it in <sys/types.h>, since both
interfaces from <sys/uio.h> and some from <sys/socket.h> use ssize_t
and/or size_t, but this should be considered accidental.

Having said that, your implementation works too.

		Cheers,

		Mark.
