Description
bool
socket_getsockname ( resource socket, string &addr [, int &port] )
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.
注:
socket_getsockname() should not be used with
AF_UNIX sockets 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.
如果成功则返回 TRUE，失败则返回 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.
