Over the past few days, I have been studying the socket program connected to. Net by Delphi, and finally made some progress. Requirements: The server intercepts the first four bytes and converts them to numbers. The second digit is the Business Code. It determines which business logic to call. Using system; using system. collections. generic; using system. text; using system. io; using system. net. sockets; using system. threading; using pivasupdate;

Socket : A communication bridge between different hosts in the network, the network communication software function that people use is based on socket socket as communication bridge.Addressing: In Winsock, users can use a unified socket address structure in the TCP/IP address family To resolve problems that may occur i

TCP Sockets Allows communication between processes through a network, or through loopback, to communicate between local processes. UNIX Sockets Allows communication between processes that are running locally. Analysis As you can see from the picture above, the UNIX socket reduces the unnecessary TCP overhead, and TCP needs to go through the loopback and request temporary ports and TCP-related resources. However, the UNIX

the socket interface is a TCP/IP network API, the socket interface defines a number of functions or routines that programmers can use to develop applications on a TCP/IP network. To learn about TCP/IP network programming on the Internet, you must understand the socket interface. The socket interface designer first plac

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.

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.

Today, qtcreator is installed in Ubuntu to test whether it can be used. As a result, a problem occurs during the test. After a simple compilation, F5 compilation appears in gnome-terminal. Cannot connect creator comm socket/tmp/qt_temp.u14973/stub-socket: no such file or directory So I checked that QT cannot be executed using gnome-terminal, and X-team is required. So I thought of the solution: Find tool

Explore UDP socket programming and udp socket programming UDP and TCP are in the same layer network model, that is, the transport layer. There are many applications based on the two. Common TCP-based applications include HTTP and Telnet, UDP-based DNS, NFS, and SNMP are available. UDP is a connectionless and unreliable data protocol service, while TCP provides stream-oriented and reliable data services. Not

After TCP programming is complete, it is UDP's turn below. This is for connectionless and simpler. Familiarize yourself with the following process: UDP socket: Server (acceptor) Program:1. Create a socket ).2. Bind the socket to a local address and port (BIND ).3. Waiting for receiving data (recvfrom ).4. Close the socket
