socket_getsockname — Queries the local side of the given socket which may either result in host/port or in a Unix filesystem path, dependent on its type
注意: socket_getsockname() should not be used with
AF_UNIXsockets created with socket_connect(). Only sockets created with socket_accept() or a primary server socket following a call to socket_bind() will return meaningful values.
socket
A Socket instance created with socket_create() or socket_accept().
address
If the given socket is of type AF_INET
or AF_INET6, socket_getsockname()
will return the local IP address in appropriate notation (e.g.
127.0.0.1 or fe80::1) in the
address parameter and, if the optional
port parameter is present, also the associated port.
If the given socket is of type AF_UNIX,
socket_getsockname() will return the Unix filesystem
path (e.g. /var/run/daemon.sock) in the
address parameter.
port
If provided, this will hold the associated port.
成功时返回 true， 或者在失败时返回 false。 socket_getsockname() may also return
false if the socket type is not any of AF_INET,
AF_INET6, or AF_UNIX, in which
case the last socket error code is not updated.
