// the <send> call). If <send> blocks for longer than <timeout> the
// number of bytes actually sent is returned with <errno == ETIME>.
// If a timeout does not occur, <send_n> return <len> (i.e., the
// number of bytes requested to be sent).

// to blocking trying to receive. If <timeout> == 0, the caller
// will block until action is possible, else will wait until the
// relative time specified in *<timeout> elapses). If <recv> blocks
// for longer than <timeout> the number of bytes actually read is
// returned with <errno == ETIME>. If a timeout does not occur,
// <recv_n> return <len> (i.e., the number of bytes requested to be
// read).
