+ * without an information structure and the eol parameter set to a positive

*
* Note that even if a single object is requested, and not the entire list,

+ * If an error occurs, the callback will be invoked without an information

* \subsection server_subsec Server Information

- * pa_context_get_server_info() will get access to a pa_server_info structure
+ * pa_context_get_server_info() provides access to a pa_server_info structure
* containing all of these.
*
* \subsection memstat_subsec Memory Usage
* \subsection sinksrc_subsec Sinks and Sources
*
* The server can have an arbitrary number of sinks and sources. Each sink
- * and source have both an index and a name associated with it. As such
+ * and source have both an index and a name associated with it. As such,
* there are three ways to get access to them:
*
* \li By index - pa_context_get_sink_info_by_index() /
* pa_context_get_module_info() or pa_context_get_module_info_list(). The
* information structure is called pa_module_info.
*
- * \subsection autoload_subsec Autoload Entries
- *
- * Modules can be autoloaded as a result of a client requesting a certain
- * sink or source. This mapping between sink/source names and modules can be
- * queried from the server:
- *
- * \li By index - pa_context_get_autoload_info_by_index()
- * \li By sink/source name - pa_context_get_autoload_info_by_name()
- * \li All - pa_context_get_autoload_info_list()
- *
* \subsection client_subsec Clients

*
* \li By index - pa_context_set_sink_volume_by_index() /
*
* If an application desires to modify the volume of just a single stream
* (commonly one of its own streams), this can be done by setting the volume

+ * pa_context_set_sink_input_volume() or pa_context_set_source_output_volume().
*
* It is also possible to remove sink inputs and source outputs, terminating
* the streams associated with them:
* Server modules can be remotely loaded and unloaded using
* pa_context_load_module() and pa_context_unload_module().
*
- * \subsection autoload_subsec Autoload Entries
