+%% File: ct_netconfc.erl
+%%
+%% Description:
+%% This file contains the Netconf client interface
+%%
+%% @author Support
+%%
+%% @doc Netconf client module.
+%%
+%% <p>The Netconf client is compliant with RFC4741 and RFC4742.</p>
+%%
+%% <p> For each server to test against, the following entry can be
+%% added to a configuration file:</p>
+%%
+%% <p>`{server_id(),options()}.'</p>
+%%
+%% <p> The `server_id()' or an associated `target_name()' (see
+%% {@link ct}) shall then be used in calls to {@link open/2}.</p>
+%%
+%% <p>If no configuration exists for a server, a session can still be
+%% opened by calling {@link open/2} with all necessary options given
+%% in the call. The first argument to {@link open/2} can then be any
+%% atom.</p>
+%%
+%% == Logging ==
+%%
+%% The netconf server uses the `error_logger' for logging of netconf
+%% traffic. A special purpose error handler is implemented in
+%% `ct_conn_log_h'. To use this error handler, add the `cth_conn_log'
+%% hook in your test suite, e.g.
+%%
+%% ```
+%% suite() ->
+%% [{ct_hooks, [{cth_conn_log, [{conn_mod(),hook_options()}]}]}].
+%%'''
+%%
+%% The `conn_mod()' is the name of the common_test module implementing
+%% the connection protocol, e.g. `ct_netconfc'.
+%%
+%% The hook option `log_type' specifies the type of logging:
+%%
+%% <dl>
+%% <dt>`raw'</dt>
+%% <dd>The sent and received netconf data is logged to a separate
+%% text file as is without any formatting. A link to the file is
+%% added to the test case HTML log.</dd>
+%%
+%% <dt>`pretty'</dt>
+%% <dd>The sent and received netconf data is logged to a separate
+%% text file with XML data nicely indented. A link to the file is
+%% added to the test case HTML log.</dd>
+%%
+%% <dt>`html (default)'</dt>
+%% <dd>The sent and received netconf traffic is pretty printed
+%% directly in the test case HTML log.</dd>
+%%
+%% <dt>`silent'</dt>
+%% <dd>Netconf traffic is not logged.</dd>
+%% </dl>
+%%
+%% By default, all netconf traffic is logged in one single log
+%% file. However, it is possible to have different connections logged
+%% in separate files. To do this, use the hook option `hosts' and
+%% list the names of the servers/connections that will be used in the
+%% suite. Note that the connections must be named for this to work,
+%% i.e. they must be opened with {@link open/2}.
+%%
+%% The `hosts' option has no effect if `log_type' is set to `html' or
+%% `silent'.
+%%
+%% The hook options can also be specified in a configuration file with
+%% the configuration variable `ct_conn_log':
+%%
+%% ```
+%% {ct_conn_log,[{conn_mod(),hook_options()}]}.
+%% '''
+%%
+%% For example:
+%%
+%% ```
+%% {ct_conn_log,[{ct_netconfc,[{log_type,pretty},
+%% {hosts,[key_or_name()]}]}]}
+%% '''
+%%
+%% <b>Note</b> that hook options specified in a configuration file
+%% will overwrite the hardcoded hook options in the test suite.
+%%
+%% === Logging example 1 ===
+%%
+%% The following `ct_hooks' statement will cause pretty printing of
+%% netconf traffic to separate logs for the connections named
+%% `nc_server1' and `nc_server2'. Any other connections will be logged
+%% to default netconf log.
+%%
+%% ```
+%% suite() ->
+%% [{ct_hooks, [{cth_conn_log, [{ct_netconfc,[{log_type,pretty}},
+%% {hosts,[nc_server1,nc_server2]}]}
+%% ]}]}].
+%%'''
+%%
+%% Connections must be opened like this:
+%%
+%% ```
+%% open(nc_server1,[...]),
+%% open(nc_server2,[...]).
+%% '''
+%%
+%% === Logging example 2 ===
+%%
+%% The following configuration file will cause raw logging of all
+%% netconf traffic into one single text file.
+%%
+%% ```
+%% {ct_conn_log,[{ct_netconfc,[{log_type,raw}]}]}.
+%% '''
+%%
+%% The `ct_hooks' statement must look like this:
+%%
+%% ```
+%% suite() ->
+%% [{ct_hooks, [{cth_conn_log, []}]}].
+%% '''
+%%
+%% The same `ct_hooks' statement without the configuration file would
+%% cause HTML logging of all netconf connections into the test case
+%% HTML log.
+%%
+%% == Notifications ==
+%%
+%% The netconf client is also compliant with RFC5277 NETCONF Event
+%% Notifications, which defines a mechanism for an asynchronous
+%% message notification delivery service for the netconf protocol.
+%%
+%% Specific functions to support this are {@link
+%% create_subscription/6} and {@link get_event_streams/3}. (The
+%% functions also exist with other arities.)
