This describes the blocking mode of the socket below:First, the socket has several functionsSocket () Create socketBind () binds the socket to an addressListen () Turn on Soket MonitorAccept () accepts others to connect me, this is a blocking

My colleague asked me today how to control the blocking time of Connect in C code under Linux. The background of the application is: Linux C program has two target IP to connect, if blocking, when one of the IP can not connect the case, the program

This program, the client through the server for group chat. The main lecture is two points: 1. How to make non-blocking mode. 2.select of rough explanation (impatient can skip, look directly at the back code) First, look at the basic logic of this

I like to explain some concepts by connecting to some phenomena in real life in my own language. When I can do this, it means that I have understood this concept. the concept to be explained today is: the difference between synchronous/asynchronous

NIO has a main class selector. This is similar to an observer. As long as we tell the selector about the socketchannel to be explored, we will continue to do other things. When an event occurs, it will notify us, return a group of selectionkeys.

From http://www.cppblog.com/converse/archive/2009/05/13/82879.html First, we will explain the concepts of synchronization and Asynchronization. Notification Mechanism of messages Related. For example, if I go to a bank to handle business

What about the Fsockopen non-blocking mode? Why is it still blocking? function Fsockopen_test () { $hostname = ' m.cn '; $url = '/test/1.php '; $fp = Fsockopen ($hostname, $errno, $ERRSTR, 5); if (! $fp) { echo "$errstr ($errno)"
