Detailed Description

Structure used to store an IPv4 address for a socket.

This structure is the standard way to set up addresses for sockets in the AF_INET address family. Generally you will not send one of these directly to a function, but rather will cast it to a struct sockaddr. Also, this structure contains the old sin_zero member which is no longer required by the standard (for compatibility with applications that expect it).
