11.4.8 Helper Functions for the Sockets Interface Thegetaddrinfofunction and the sockets interface can seem somewhere daunting when you first learn about them. We find it convinient to wrap them with higher-level helper functions, calledopen_clientfdandopen_listenfd, that clients and servers can ...

A socket is an endpoint of communication to which a name can be bound. A socket has a type and one associated process. Sockets were designed to implement the client-server model for interprocess communication where: The interface to network protocols needs to accommodate multiple communication ...
The bind(3SOCKET) interface enables a process to specify the local address of the socket. This interface forms the local address, local port set. connect(3SOCKET) and accept(3SOCKET) complete a socket's association by fixing the remote half of the address tuple. The bind(3SOCKET) call is...
