示例1: Recv

// Recv receives a message.  For AF_SP_RAW messages the header data will
// be included at he start of the returned byte slice (otherwise it will
// be stripped).  At this time no flags are supported.
func (s *Socket) Recv(flags int) ([]byte, error) {
	var b []byte
	var m *mangos.Message
	var err error

	if flags != 0 {
		return nil, errNoFlag
	}

	// Legacy nanomsg uses the opposite semantic for negative and
	// zero values than mangos.  A bit unfortunate.
	switch {
	case s.rto > 0:
		s.sock.SetOption(mangos.OptionRecvDeadline, s.rto)
	case s.rto == 0:
		s.sock.SetOption(mangos.OptionRecvDeadline, -1)
	case s.rto < 0:
		s.sock.SetOption(mangos.OptionRecvDeadline, 0)
	}

	if m, err = s.sock.RecvMsg(); err != nil {
		return nil, err
	}

	if s.dom == AF_SP_RAW {
		b = make([]byte, 0, len(m.Body)+len(m.Header))
		b = append(b, m.Header...)
		b = append(b, m.Body...)
	} else {
		b = make([]byte, 0, len(m.Body))
		b = append(b, m.Body...)
	}
	m.Free()

示例2: SendHook

func (r *req) SendHook(m *mangos.Message) bool {

		// request id in the header coming down.

	}

	defer r.Unlock()

	// We need to generate a new request id, and append it to the header.
	r.reqid = r.nextID()
	v := r.reqid
	m.Header = append(m.Header,
		byte(v>>24), byte(v>>16), byte(v>>8), byte(v))

	r.reqmsg = m.Dup()

	// Schedule a retry, in case we don't get a reply.
	if r.retry > 0 {
		r.waker.Reset(r.retry)
	} else {
		r.waker.Stop()
	}

	r.sock.SetRecvError(nil)

示例6: RecvHook

// We save the backtrace from this message.  This means that if the app calls
