These functions allow to manage connections to upsd(8) using NUT TCP protocol.

The nutclient_tcp_create_client() function create the NUTCLIENT_TCP_t context and intend to connect to upsd at host and port. The context must be freed by nutclient_destroy()

• host can be a sever name or a valid IPv4 or IPv6 address like "localhost", "127.0.0.1" or "::1".
• port is a valid TCP port, generally 3493.

The nutclient_tcp_is_connected() function test if the connection is valid.

The nutclient_tcp_disconnect() function force to disconnect the specified connection.

The nutclient_tcp_reconnect() function force to reconnect a connection, disconnecting it if needed.

The nutclient_tcp_set_timeout() function set the timeout duration for I/O operations.

The nutclient_tcp_get_timeout() function retrieve the timeout duration for I/O operations.

timeout values are specified in seconds, negatives values for blocking.
