What is socket 　　A socket interface is an API of a TCP/IP network. A socket interface defines many functions or routines. programmers can use it to develop applications on a TCP/IP network. To learn TCP/IP network programming on the internet, you

Send functionint send (SOCKET s, const char far *buf, int len, int flags);Both the client and the server application use the Send function to send data to the other end of the TCP connection.The client program typically sends a request to the server

Phenomenon:On a Windows 7 system, a uses a UDP socket, which calls the SendTo function to send data to a destination address B, but the destination address B does not receive data, and if a immediately calls Recvfrom to attempt to receive the data

Here, the thread model refers to the thread model design related to Winsock. Some problems in the design process of this software involve Winsock. In order to design the thread model well, we must understand the internal working mechanism of socket.

1 UDP Receive principleThe UDP receiving process of the operating system is as follows: After receiving a UDP packet, after verifying that there is no error, put in a package queue, each element in the queue is a complete UDP packet. When the
