Two I/O modes 1. Two I/O modes Blocking mode: Waits until the execution of an I/O operation completes without handing control over to the program. The socket defaults to blocking mode. Can be processed through multithreading techniques. Non-blocking

Send blockingThe socket recv send interface is blocked, which causes the server side not to respond to any requests from the client, so the socket is set to a non-blocking state in general.However, some scenarios, such as ssl_accept, need to use a

1. Select Model:Select model: Through a Fd_set collection management socket, after the socket requirements are met, the socket is notified. Let the socket work. Avoid sockets entering blocking mode and making unnecessary waits. Select the Fd_set

Blocking Model int recv (SOCKET S,char* buf,int Len,int flags); int Send (SOCKET S,Const char* BUF,int Len,int flags); This way is most familiar, the socket default is blocking mode.In recv, the socket blocks there

To network programming is to deal with the socket, the socket has synchronous blocking mode and asynchronous non-blocking mode two use, in fact, synchronous and asynchronous in our programming career may encounter a lot, and the socket is nothing

March 12, 2002 The Java technology platform should have provided non-blocking I/O mechanisms for a long time. Fortunately, Merlin (JDK 1.4) has a magic wand that applies in almost every scenario, and the blocking state of the blocked I/O is

During network programming, we often see four call Methods: synchronous, asynchronous, blocking, and non-blocking. These methods are not easy to understand. The following is my understanding of these terms.SynchronizationThe so-called

1 Introduction The Windows Sockets Specification defines a set of network programming interfaces in Microsoft Windows based on the socket interface popular in U. C. Berkeley University bsd unix. It not only contains the familiar Berkeley socket

I. synchronous and asynchronousSynchronous/asynchronous, which are notifications of messages1. ConceptsA. SynchronizationThe so-called synchronization means that when a function call is sent, the call will not return until the result is not obtained.

Apache axis2 is a successor to the Apache axis soap project. This project is an important improvement of the core web service engine. It aims to become the next-generation platform for web services and service-oriented Architecture (SOA. As a clean

Http://hj490134273.blog.163.com/blog/static/1446496162010494441182/ I just started to learn socket programming. I just made a simple chat room program. Later I went deep into it and found many problems, first, let's talk about the three socket usage

During network programming, we often see four call Methods: synchronous, asynchronous, blocking, and non-blocking. These methods are not easy to understand. The following is my understanding of these terms. SynchronizationThe so-called

First, we will introduce blocking and non-blocking:What is blocking? For example, you are waiting for the express delivery at some time, but you do not know when the express delivery will come, and you have nothing to do (or the next thing must be

1. Background 1.1. Amazing performance dataRecently a friend in the circle told me that by using NETTY4 + Thrift Compression Binary codec technology, they implemented a cross-node remote service invocation of 10W TPS (1K complex Pojo objects).
