37 /** \page introspect Server Query and Control
39 * \section overv_sec Overview
41 * Sometimes it is necessary to query and modify global settings in the
42 * server. For this, PulseAudio has the introspection API. It can list sinks,
43 * sources, samples and other aspects of the server. It can also modify the
44 * attributes of the server that will affect operations on a global level,
45 * and not just the application's context.
47 * \section query_sec Querying
49 * All querying is done through callbacks. This design is necessary to
50 * maintain an asynchronous design. The client will request the information
51 * and some time later, the server will respond with the desired data.
53 * Some objects can have multiple entries at the server. When requesting all
54 * of these at once, the callback will be called multiple times, once for
55 * each object. When the list has been exhausted, the callback will be called
56 * without an information structure and the eol parameter set to a non-zero
59 * Note that even if a single object is requested, and not the entire list,
60 * the terminating call will still be made.
62 * If an error occurs, the callback will be called without and information
63 * structure and eol set to zero.
65 * Data members in the information structures are only valid during the
66 * duration of the callback. If they are required after the callback is
67 * finished, a deep copy must be performed.
69 * \subsection server_subsec Server Information
71 * The server can be queried about its name, the environment it's running on
72 * and the currently active global defaults. Calling
73 * pa_context_get_server_info() will get access to a pa_server_info structure
74 * containing all of these.
76 * \subsection memstat_subsec Memory Usage
78 * Statistics about memory usage can be fetched using pa_context_stat(),
79 * giving a pa_stat_info structure.
81 * \subsection sinksrc_subsec Sinks and Sources
83 * The server can have an arbitrary number of sinks and sources. Each sink
84 * and source have both an index and a name associated with it. As such
85 * there are three ways to get access to them:
87 * \li By index - pa_context_get_sink_info_by_index() /
88 * pa_context_get_source_info_by_index()
89 * \li By name - pa_context_get_sink_info_by_name() /
90 * pa_context_get_source_info_by_name()
91 * \li All - pa_context_get_sink_info_list() /
92 * pa_context_get_source_info_list()
94 * All three method use the same callback and will provide a pa_sink_info or
95 * pa_source_info structure.
97 * \subsection siso_subsec Sink Inputs and Source Outputs
99 * Sink inputs and source outputs are the representations of the client ends
100 * of streams inside the server. I.e. they connect a client stream to one of
101 * the global sinks or sources.
103 * Sink inputs and source outputs only have an index to identify them. As
104 * such, there are only two ways to get information about them:
106 * \li By index - pa_context_get_sink_input_info() /
107 * pa_context_get_source_output_info()
108 * \li All - pa_context_get_sink_input_info_list() /
109 * pa_context_get_source_output_info_list()
111 * The structure returned is the pa_sink_input_info or pa_source_output_info
114 * \subsection samples_subsec Samples
116 * The list of cached samples can be retrieved from the server. Three methods
117 * exist for querying the sample cache list:
119 * \li By index - pa_context_get_sample_info_by_index()
120 * \li By name - pa_context_get_sample_info_by_name()
121 * \li All - pa_context_get_sample_info_list()
123 * Note that this only retrieves information about the sample, not the sample
126 * \subsection module_subsec Driver Modules
128 * PulseAudio driver modules are identified by index and are retrieved using either
129 * pa_context_get_module_info() or pa_context_get_module_info_list(). The
130 * information structure is called pa_module_info.
132 * \subsection autoload_subsec Autoload Entries
134 * Modules can be autoloaded as a result of a client requesting a certain
135 * sink or source. This mapping between sink/source names and modules can be
136 * queried from the server:
138 * \li By index - pa_context_get_autoload_info_by_index()
139 * \li By sink/source name - pa_context_get_autoload_info_by_name()
140 * \li All - pa_context_get_autoload_info_list()
142 * \subsection client_subsec Clients
144 * PulseAudio clients are also identified by index and are retrieved using
145 * either pa_context_get_client_info() or pa_context_get_client_info_list().
146 * The information structure is called pa_client_info.
148 * \section ctrl_sec Control
150 * Some parts of the server are only possible to read, but most can also be
151 * modified in different ways. Note that these changes will affect all
152 * connected clients and not just the one issuing the request.
154 * \subsection sinksrc_subsec Sinks and Sources
156 * The most common change one would want to do to sinks and sources is to
157 * modify the volume of the audio. Identical to how sinks and sources can
158 * be queried, there are two ways of identifying them:
160 * \li By index - pa_context_set_sink_volume_by_index() /
161 * pa_context_set_source_volume_by_index()
162 * \li By name - pa_context_set_sink_volume_by_name() /
163 * pa_context_set_source_volume_by_name()
165 * It is also possible to mute a sink or source:
167 * \li By index - pa_context_set_sink_mute_by_index() /
168 * pa_context_set_source_mute_by_index()
169 * \li By name - pa_context_set_sink_mute_by_name() /
170 * pa_context_set_source_mute_by_name()
172 * \subsection siso_subsec Sink Inputs and Source Outputs
174 * If an application desires to modify the volume of just a single stream
175 * (commonly one of its own streams), this can be done by setting the volume
176 * of its associated sink input, using pa_context_set_sink_input_volume().
178 * There is no support for modifying the volume of source outputs.
180 * It is also possible to remove sink inputs and source outputs, terminating
181 * the streams associated with them:
183 * \li Sink input - pa_context_kill_sink_input()
184 * \li Source output - pa_context_kill_source_output()
186 * \subsection module_subsec Modules
188 * Server modules can be remotely loaded and unloaded using
189 * pa_context_load_module() and pa_context_unload_module().
191 * \subsection autoload_subsec Autoload Entries
193 * New module autoloading rules can be added, and existing can be removed
194 * using pa_context_add_autoload() and pa_context_remove_autoload_by_index()
195 * / pa_context_remove_autoload_by_name().
197 * \subsection client_subsec Clients
199 * The only operation supported on clients, is the possibility of kicking
200 * them off the server using pa_context_kill_client().
205 * Routines for daemon introspection.
