NAME

libnutclient_tcp, nutclient_tcp_create_client, nutclient_tcp_is_connected, nutclient_tcp_disconnect, nutclient_tcp_reconnect, nutclient_tcp_set_timeout, nutclient_tcp_get_timeout - 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 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 adress like "localhost", "127.0.0.1" or "::1". port is a valid TCP port, genrally 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.
