参数
- socket

- address
-
The address parameter is either an IPv4 address in dotted-quad notation (e.g. 127.0.0.1) if socket is AF_INET, a valid IPv6 address (e.g. ::1) if IPv6 support is enabled and socket is AF_INET6 or the pathname of a Unix domain socket, if the socket family is AF_UNIX.
- port
-
The port parameter is only used and is mandatory when connecting to an AF_INET or an AF_INET6 socket, and designates the port on the remote host to which a connection should be made.
返回值
如果成功则返回 TRUE，失败则返回 FALSE。 The error code can be retrieved with socket_last_error(). This code may be passed to socket_strerror() to get a textual explanation of the error.
Note: If the socket is non-blocking then this function returns FALSE with an error Operation now in progress.
