TCP protocol related function for Network UPS Tools high-level client access library

SYNOPSIS
--------

	#include <nutclient.h>

	typedef NUTCLIENT_t NUTCLIENT_TCP_t;

	NUTCLIENT_TCP_t nutclient_tcp_create_client(const char* host, unsigned short port);
	int nutclient_tcp_is_connected(NUTCLIENT_TCP_t client);
	void nutclient_tcp_disconnect(NUTCLIENT_TCP_t client);
	int nutclient_tcp_reconnect(NUTCLIENT_TCP_t client);
	void nutclient_tcp_set_timeout(NUTCLIENT_TCP_t client, long timeout);
	long nutclient_tcp_get_timeout(NUTCLIENT_TCP_t client);	

DESCRIPTION
-----------

These functions allow to manage connections to linkman: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.
