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.
