Socket network programming first, socket first First, I would like to summarize some of the books required for job interviews: I suddenly felt very steadfast in my mind, "the beauty of programming", "The sword refers to offer", "Unix environment programming", "Unix network programming", and "POSIX multi-thread programming, I am no longer confused. I finally know what I can do after I graduated from the comp

The reason is that this will produce a server instead of a Web page. If you try to run the script using a Web browser, chances are that it will exceed the 30-second limit. You can use the following code to set an unlimited run time, but it is recommended that y

stream. 2. The shutdowninput () and shutdownoutput () Methods of socket are called successively. They only close the input stream and output stream, and are not equivalent to the close () method of socket. After the communication ends, you still need to call the close () method of the socket, because only this method can release the resources occupied by the

entry. When you call the socket function, the socket executor creates a socket, in effect "building a socket" means allocating storage space for a socket data structure. The socket executor manages the descriptor table for you. A

You can check the phpinfo information to check whether the socket is enabled. For example: View the socket information of phpinfo () ◆ generate a

Http://blogold.chinaunix.net/u1/43206/showart_518836.htmlSocket INADDR_ANY listens to the 0.0.0.0 address. The socket only binds the port so that the route table decides which ip address to transfer.INADDR_ANY indicates the address 0.0.0.0. In fact, this address indicates an uncertain address, "all addresses", or "any address ".Generally, if you want to create a network server, you need to notify the server operating system at a specific address xxx.

This causes its TCP to send also a fin N; This fin is received by the source send side TCP to confirm it. So there is a fin and an ack in each dir
