//! bound to a local address with bind(), and is listening for
//! connections after a listen(). The argument addr is a pointer
//! to a sockaddr structure. This structure is filled in with the
//! address of the peer socket, as known to the communications layer.
//! The exact format of the address returned addr is determined by the
//! socket's address family. The addrlen argument is a value-result
//! argument: it should initially contain the size of the structure
//! pointed to by addr, on return it will contain the actual
//! length (in bytes) of the address returned.
