winsock dll

What is Winsock? Winsock is a network programming interface in windows. It is developed from BSD socket in UNIX and is a programming interface unrelated to the network protocol. Build a programming environment Winsock has two major versions on common Windows platforms: winsock1 and Winsock2. Write compatible with winsock1ProgramYou need to reference the hea

WinSock network programming BASICS (1) and winsock network programming Basics Record the problems encountered during windows Network Programming and related notes Basic concepts: Socket: Socket originated from UNIX. Socket is an intermediate software abstraction layer for communications between the application layer and the TCP/IP protocol family. It is a set of interfaces. Based on the "open-read/write-Clo

Basic Winsock programming and winsock programmingBasic Winsock programming The original meaning of Socket is "hole" or "Socket ". As the process Communication Mechanism of bsd unix, take the latter meaning. It is also called "socket". It is used to describe the IP address and port and is a communication chain handle. Hosts on the Internet generally run multiple s

WinSock network programming BASICS (3) server and winsock network programming In the previous article, we talked about the implementation of a simple client for sending data. Next we will talk about how to send and receive data servers.The server mentioned here is actually a process. It needs to wait for any number of clients to establish a connection with it to respond to their requests. The server must li

Learn about the Winsock API and refer to the server example in the book. The source code is as follows: /** File: Server. cpp**/ # Include # Include # Include # Define default_port 5150.# Define default_buffer 4096.Int iport = default_port; Bool binterface = true;Bool brecvonly = false;Char szaddress [128];// Function: Usage// Description:// Print usage information and exitVoid usage (){Printf ("Usage: Server [-P: X] [-I: IP] [-O]/n ");Printf ("-P: X

packet loss occurs. Otherwise,Because when they use a large enough buffer, they may receive twoTo more data packets, and many people tend to ignore this point, only the firstBut other received data packets are ignored.You must pay attention to this when programming the network of the class. 4. Simple Winsock programming process Next we will introduce the Winsock programming method on the Win32 platform.Com

WinSock programming Currently, Internet has become the world's largest TCP/IP network. Early websites were Unix machines, and a set of conventions known as the Berkeley plug-in became the standard for communications between Unix machines on the Internet using TCP/IP. Other operating systems also use TCP/IP for communication, which greatly promotes the development of the Internet. Windows plug-in The Winso
