在select/poll中,进程只有在调用一定的方法后,内核才对所有监视的文件描述符进行扫描,而epoll事先通过epoll_ctl()来注册一个文件描述符,一旦基于某个文件描述符就绪时,内核会采用类似callback的回调机制,迅速激活这个文件描述符,当进程调用epoll_wait()时便得到通知。 select 多并发socket 实例 select socket server:...

The caller may set theSocketAsyncEventArgs.UserTokenproperty to any user state object desired before calling theReceiveFromAsyncmethod, so that the information will be retrievable in the callback method. If the callback needs more information than a single object, a small class can be created to...
