Arguments of the Message Handler Plug-in Initialize Function

The ffh_mh_info argument of the initialize function specifies the release_message and shutdown callbacks that should be used by the plug-in to release no longer needed ffh_fast_message instances, or to request shutdown of the FAST feed handler.

ffh_mh_info->user_data can be used by the plug-in to store a pointer to an instance of its message handler class for future reference.

The plug-in should save a reference to the ffh_mh_info argument so that it can use it in its implementation of the shutdown() function required by the publisher API. In that shutdown() function, the plug-in should invoke the shutdown callback specified in the ffh_mh_info object.

The ffh_init_param argument of the initialize function contains the values and the names of the initParam elements from the configuration file. It can be used to pass information needed to initialize the publisher API (for example, the publisher configuration directory and the RDS templates directory).
