In case of a TCP socket, it causes an attempt to establish a new TCP connection. accept() is used on the server side. It accepts a received incoming attempt to create a new TCP connection from the remote client, and creates a new socket associated with the socket address pair of this connection. send() and recv(), or write().

Sep 21, 2014. This code is compiled and run on the Raspberry as follows: g++ -o myServer myServer.c./myServer The server waits for a connection request from a client. The server assumes the client will send positive integers, which it sends back multiplied by 2. If the server receives -1 it closes the socket with the client.

From the client program's point of view, you must perform the following general steps: Create a socket. Optionally bind the socket (to restrict which interface will be used, or to explicitly indicate a wild socket address). Connect to the remote socket (client connects to the server). Communicate with reads and writes. Shut down.

Learn network programming & socket programming quickly, use async/await for network I/O, build your own class library

So first, let's make a distinction between a “client” socket – an endpoint of a conversation, and a “server” socket, which is more like a switchboard operator. The client application (your browser, for example) uses “client” sockets exclusively; the web server it's talking to uses both “server” sockets and “client” sockets.
