For this, PulseAudio has the introspection API. It can list sinks, 42 * sources, samples and other aspects of the server. It can also modify the 43 * attributes of the server that will affect operations on a global level, 44 * and not just the application's context. 45 * 46 * \section query_sec Querying 47 * 48 * All querying is done through callbacks. This design is necessary to 49 * maintain an asynchronous design. The client will request the information 50 * and some time later, the server will respond with the desired data. 51 * 52 * Some objects can have multiple entries at the server. When requesting all 53 * of these at once, the callback will be called multiple times, once for 54 * each object. When the list has been exhausted, the callback will be called 55 * without an information structure and the eol parameter set to a non-zero 56 * value. 57 * 58 * Note that even if a single object is requested, and not the entire list, 59 * the terminating call will still be made. 60 * 61 * If an error occurs, the callback will be called without and information 62 * structure and eol set to zero. 63 * 64 * Data members in the information structures are only valid during the 65 * duration of the callback. If they are required after the callback is 66 * finished, a deep copy must be performed. 67 * 68 * \subsection server_subsec Server Information 69 * 70 * The server can be queried about its name, the environment it's running on 71 * and the currently active global defaults. Calling 72 * pa_context_get_server_info() will get access to a pa_server_info structure 73 * containing all of these. 74 * 75 * \subsection memstat_subsec Memory Usage 76 * 77 * Statistics about memory usage can be fetched using pa_context_stat(), 78 * giving a pa_stat_info structure. 79 * 80 * \subsection sinksrc_subsec Sinks and Sources 81 * 82 * The server can have an arbitrary number of sinks and sources. Each sink 83 * and source have both an index and a name associated with it. As such 84 * there are three ways to get access to them: 85 * 86 * \li By index - pa_context_get_sink_info_by_index() / 87 * pa_context_get_source_info_by_index() 88 * \li By name - pa_context_get_sink_info_by_name() / 89 * pa_context_get_source_info_by_name() 90 * \li All - pa_context_get_sink_info_list() / 91 * pa_context_get_source_info_list() 92 * 93 * All three method use the same callback and will provide a pa_sink_info or 94 * pa_source_info structure. 95 * 96 * \subsection siso_subsec Sink Inputs and Source Outputs 97 * 98 * Sink inputs and source outputs are the representations of the client ends 99 * of streams inside the server. I.e. they connect a client stream to one of 100 * the global sinks or sources. 101 * 102 * Sink inputs and source outputs only have an index to identify them. As 103 * such, there are only two ways to get information about them: 104 * 105 * \li By index - pa_context_get_sink_input_info() / 106 * pa_context_get_source_output_info() 107 * \li All - pa_context_get_sink_input_info_list() / 108 * pa_context_get_source_output_info_list() 109 * 110 * The structure returned is the pa_sink_input_info or pa_source_output_info 111 * structure. 112 * 113 * \subsection samples_subsec Samples 114 * 115 * The list of cached samples can be retrieved from the server. Three methods 116 * exist for querying the sample cache list: 117 * 118 * \li By index - pa_context_get_sample_info_by_index() 119 * \li By name - pa_context_get_sample_info_by_name() 120 * \li All - pa_context_get_sample_info_list() 121 * 122 * Note that this only retrieves information about the sample, not the sample 123 * data itself. 124 * 125 * \subsection module_subsec Driver Modules 126 * 127 * PulseAudio driver modules are identified by index and are retrieved using either 128 * pa_context_get_module_info() or pa_context_get_module_info_list(). The 129 * information structure is called pa_module_info. 130 * 131 * \subsection autoload_subsec Autoload Entries 132 * 133 * Modules can be autoloaded as a result of a client requesting a certain 134 * sink or source. This mapping between sink/source names and modules can be 135 * queried from the server: 136 * 137 * \li By index - pa_context_get_autoload_info_by_index() 138 * \li By sink/source name - pa_context_get_autoload_info_by_name() 139 * \li All - pa_context_get_autoload_info_list() 140 * 141 * \subsection client_subsec Clients 142 * 143 * PulseAudio clients are also identified by index and are retrieved using 144 * either pa_context_get_client_info() or pa_context_get_client_info_list(). 145 * The information structure is called pa_client_info. 146 * 147 * \section ctrl_sec Control 148 * 149 * Some parts of the server are only possible to read, but most can also be 150 * modified in different ways. Note that these changes will affect all 151 * connected clients and not just the one issuing the request. 152 * 153 * \subsection sinksrc_subsec Sinks and Sources 154 * 155 * The most common change one would want to do to sinks and sources is to 156 * modify the volume of the audio. Identical to how sinks and sources can 157 * be queried, there are two ways of identifying them: 158 * 159 * \li By index - pa_context_set_sink_volume_by_index() / 160 * pa_context_set_source_volume_by_index() 161 * \li By name - pa_context_set_sink_volume_by_name() / 162 * pa_context_set_source_volume_by_name() 163 * 164 * It is also possible to mute a sink or source: 165 * 166 * \li By index - pa_context_set_sink_mute_by_index() / 167 * pa_context_set_source_mute_by_index() 168 * \li By name - pa_context_set_sink_mute_by_name() / 169 * pa_context_set_source_mute_by_name() 170 * 171 * \subsection siso_subsec Sink Inputs and Source Outputs 172 * 173 * If an application desires to modify the volume of just a single stream 174 * (commonly one of its own streams), this can be done by setting the volume 175 * of its associated sink input, using pa_context_set_sink_input_volume(). 176 * 177 * There is no support for modifying the volume of source outputs. 178 * 179 * It is also possible to remove sink inputs and source outputs, terminating 180 * the streams associated with them: 181 * 182 * \li Sink input - pa_context_kill_sink_input() 183 * \li Source output - pa_context_kill_source_output() 184 * 185 * \subsection module_subsec Modules 186 * 187 * Server modules can be remotely loaded and unloaded using 188 * pa_context_load_module() and pa_context_unload_module(). 189 * 190 * \subsection autoload_subsec Autoload Entries 191 * 192 * New module autoloading rules can be added, and existing can be removed 193 * using pa_context_add_autoload() and pa_context_remove_autoload_by_index() 194 * / pa_context_remove_autoload_by_name(). 195 * 196 * \subsection client_subsec Clients 197 * 198 * The only operation supported on clients, is the possibility of kicking 199 * them off the server using pa_context_kill_client(). 200 */ 201 202 /** \file 203 * 204 * Routines for daemon introspection. 205 */ 206 207 PA_C_DECL_BEGIN 208 209 /** Stores information about sinks */ 210 typedef struct pa_sink_info { 211 const char *name;
