Reference: Linux high-performance Server programming, game double Program Description: This program uses the shared memory to synchronize between processes. Because it only reads shared memory at the same time, no locks are used. The function of this program is that the server listens to network connections. When a client connects, the server creates a sub-process to process the connection. Each sub-process is only responsible for communicating with i

is closed, recv in the thread returns 0, exits the loop, and exits the thread. At this point B will exit the program if CTRL+D is pressed.2. After one party presses the ctrl+d, the other party immediately presses the ctrl+d. The two sides were deadlocked. If one party presses CTRL + C, the other party will follow the withdrawal after forcing the program to exit. Cause: One side is strong, causing the socket port to really shut down, recv in the other side of the child thread returns 0, exits th

It is similar to writing a server-side program code under the TCP protocol, but because it is a non-connected form, there is no need to listen.This time, I used a little different idea: I set up a server, with two ports and two sockets, the server as a data forwarding station, so that the client to the UDP protocol communication.Service-Side code:/** * UDP/IP Server-side SERVER.C */#include But there will be a small problem, the first data sent to the client's data can not be received, and to ru

The TCP protocol is similar to when the caller is on the phone and is talking to each other at the moment. Ensure that both parties are online in order to transfer data. UDP protocol is like a mailbox, does not guarantee that the other party must be waiting for your mail and the other side you can also send data to each other. In fact, the TCP protocol, UDP protocol, there are important TCP protocol three handshake (establish connection) and four waves (close connection) and so on the Internet a
