Golang zframe_more Examples

Example #1

File: sock.go Project: vonwenm/goczmq

// RecvFrame reads a frame from the socket and returns it
// as a byte array, along with a more flag and and error
// (if there is an error)
func (s *Sock) RecvFrame() ([]byte, int, error) {
	frame := C.zframe_recv(unsafe.Pointer(s.zsockT))
	if frame == nil {
		return []byte{0}, 0, errors.New("failed")
	}
	dataSize := C.zframe_size(frame)
	dataPtr := C.zframe_data(frame)
	b := C.GoBytes(unsafe.Pointer(dataPtr), C.int(dataSize))
	more := C.zframe_more(frame)
	C.zframe_destroy(&frame)
	return b, int(more), nil
}
