* NAME
* c_complain
*
* DESCRIPTION
* Complain about something. This function will report a message (usually
* indicating some error condition) using the collectd logging mechanism.
* When this function is called again, reporting the message again will be
* deferred by an increasing interval (up to one day) to prevent flooding
* the logs. A call to `c_release' resets the counter.
*
* PARAMETERS
* `level' The log level passed to `plugin_log'.
* `c' Identifier for the complaint.
* `format' Message format - see the documentation of printf(3).

* DESCRIPTION
* Complain about something once. This function will not report anything
* again, unless `c_release' has been called in between. If used after some
* calls to `c_complain', it will report again on the next interval and stop
* after that.
*
* See `c_complain' for further details and a description of the parameters.
