示例1: Add
// Add registers a socket for sending and/or receiving. The caller can't
// access the socket directly after this. The send channel (if any) should be
// closed by the caller.
func (io *IO) Add(s *zmq.Socket, send <-chan Data, recv chan<- Data) (err error) {
fd, err := s.GetFd()
if err != nil {
return
}
w := newWorker()
io.lock.Lock()
io.workers[int32(fd)] = w
io.lock.Unlock()
defer func() {
if err != nil {
io.lock.Lock()
delete(io.workers, int32(fd))
io.lock.Unlock()
}
}()
e := &syscall.EpollEvent{
Events: syscall.EPOLLIN | syscall.EPOLLET&0xffffffff,
Fd: int32(fd),
}
if err = syscall.EpollCtl(io.epollFd, syscall.EPOLL_CTL_ADD, fd, e); err != nil {
return
}
state, err := s.GetEvents()
if err != nil {
syscall.EpollCtl(io.epollFd, syscall.EPOLL_CTL_DEL, fd, nil)
return
}
go func() {
defer s.Close()
defer syscall.EpollCtl(io.epollFd, syscall.EPOLL_CTL_DEL, fd, nil)
w.socketLoop(s, send, recv, state)
}()
return
}示例2: Remove
// Remove closes a socket. If it has been registered, it will be removed. The
// recv channel (if any) will be closed.
func (io *IO) Remove(s *zmq.Socket) (err error) {
fd, err := s.GetFd()
if err != nil {
return
}
io.lock.Lock()
w := io.workers[int32(fd)]
if w != nil {
delete(io.workers, int32(fd))
}
io.lock.Unlock()
if w != nil {
w.close()
} else {
err = s.Close()
}
return
}
