aarch64: add pulse audio headers
BUG: 152456395
BUG: 146226835
The default system pulse header (/usr/include/pulse) will
have conflicts to the ones used by the qemu.
so make a copy from prebuilts/gcc/linux-x86/host/ \
x86_64-linux-glibc2.17-4.8/sysroot/usr/include/pulse
to make headless pulse audio compile.

+/** \page channelmap Channel Maps
+ *
+ * \section overv_sec Overview
+ *
+ * Channel maps provide a way to associate channels in a stream with a
+ * specific speaker position. This relieves applications of having to
+ * make sure their channel order is identical to the final output.
+ *
+ * \section init_sec Initialisation
+ *
+ * A channel map consists of an array of \ref pa_channel_position values,
+ * one for each channel. This array is stored together with a channel count
+ * in a pa_channel_map structure.
+ *
+ * Before filling the structure, the application must initialise it using
+ * pa_channel_map_init(). There are also a number of convenience functions
+ * for standard channel mappings:
+ *
+ * \li pa_channel_map_init_mono() - Create a channel map with only mono audio.
+ * \li pa_channel_map_init_stereo() - Create a standard stereo mapping.
+ * \li pa_channel_map_init_auto() - Create a standard channel map for a specific number of channels
+ * \li pa_channel_map_init_extend() - Similar to
+ * pa_channel_map_init_auto() but synthesize a channel map if no
+ * predefined one is known for the specified number of channels.
+ *
+ * \section conv_sec Convenience Functions
+ *
+ * The library contains a number of convenience functions for dealing with
+ * channel maps:
+ *
+ * \li pa_channel_map_valid() - Tests if a channel map is valid.
+ * \li pa_channel_map_equal() - Tests if two channel maps are identical.
+ * \li pa_channel_map_snprint() - Creates a textual description of a channel
+ * map.

+/** \page async Asynchronous API
+ *
+ * \section overv_sec Overview
+ *
+ * The asynchronous API is the native interface to the PulseAudio library.
+ * It allows full access to all available functionality. This however means that
+ * it is rather complex and can take some time to fully master.
+ *
+ * \section mainloop_sec Main Loop Abstraction
+ *
+ * The API is based around an asynchronous event loop, or main loop,
+ * abstraction. This abstraction contains three basic elements:
+ *
+ * \li Deferred events - Events that will trigger as soon as possible. Note
+ * that some implementations may block all other events
+ * when a deferred event is active.
+ * \li I/O events - Events that trigger on file descriptor activities.
+ * \li Times events - Events that trigger after a fixed amount of time.
+ *
+ * The abstraction is represented as a number of function pointers in the
+ * pa_mainloop_api structure.
+ *
+ * To actually be able to use these functions, an implementation needs to
+ * be coupled to the abstraction. There are three of these shipped with
+ * PulseAudio, but any other can be used with a minimal amount of work,
+ * provided it supports the three basic events listed above.
+ *
+ * The implementations shipped with PulseAudio are:
+ *
+ * \li \subpage mainloop - A minimal but fast implementation based on poll().
+ * \li \subpage threaded_mainloop - A special version of the previous
+ * implementation where all of PulseAudio's
+ * internal handling runs in a separate
+ * thread.
+ * \li \subpage glib-mainloop - A wrapper around GLib's main loop.
+ *
+ * UNIX signals may be hooked to a main loop using the functions from
+ * \ref mainloop-signal.h. These rely only on the main loop abstraction
+ * and can therefore be used with any of the implementations.
+ *
+ * \section refcnt_sec Reference Counting
+ *
+ * Almost all objects in PulseAudio are reference counted. What that means
+ * is that you rarely malloc() or free() any objects. Instead you increase
+ * and decrease their reference counts. Whenever an object's reference
+ * count reaches zero, that object gets destroy and any resources it uses
+ * get freed.
+ *
+ * The benefit of this design is that an application need not worry about
+ * whether or not it needs to keep an object around in case the library is
+ * using it internally. If it is, then it has made sure it has its own
+ * reference to it.
+ *
+ * Whenever the library creates an object, it will have an initial
+ * reference count of one. Most of the time, this single reference will be
+ * sufficient for the application, so all required reference count
+ * interaction will be a single call to the objects unref function.
+ *
+ * \section context_sec Context
+ *
+ * A context is the basic object for a connection to a PulseAudio server.
+ * It multiplexes commands, data streams and events through a single
+ * channel.
+ *
+ * There is no need for more than one context per application, unless
+ * connections to multiple servers are needed.
+ *
+ * \subsection ops_subsec Operations
+ *
+ * All operations on the context are performed asynchronously. I.e. the
+ * client will not wait for the server to complete the request. To keep
+ * track of all these in-flight operations, the application is given a
+ * pa_operation object for each asynchronous operation.
+ *
+ * There are only two actions (besides reference counting) that can be
+ * performed on a pa_operation: querying its state with
+ * pa_operation_get_state() and aborting it with pa_operation_cancel().
+ *
+ * A pa_operation object is reference counted, so an application must
+ * make sure to unreference it, even if it has no intention of using it.
+ *
+ * \subsection conn_subsec Connecting
+ *
+ * A context must be connected to a server before any operation can be
+ * issued. Calling pa_context_connect() will initiate the connection
+ * procedure. Unlike most asynchronous operations, connecting does not
+ * result in a pa_operation object. Instead, the application should

+ *
+ * Since the context object has references to other objects it must be
+ * disconnected after use or there is a high risk of memory leaks. If the
+ * connection has terminated by itself, then there is no need to explicitly
+ * disconnect the context using pa_context_disconnect().

+/** \page introspect Server Query and Control
+ *
+ * \section overv_sec Overview
+ *
+ * Sometimes it is necessary to query and modify global settings in the
+ * server. For this, PulseAudio has the introspection API. It can list sinks,
+ * sources, samples and other aspects of the server. It can also modify the
+ * attributes of the server that will affect operations on a global level,
+ * and not just the application's context.
+ *
+ * \section query_sec Querying
+ *
+ * All querying is done through callbacks. This approach is necessary to
+ * maintain an asynchronous design. The client will request the information
+ * and some time later, the server will respond with the desired data.
+ *
+ * Some objects can have multiple instances on the server. When requesting all
+ * of these at once, the callback will be called multiple times, once for
+ * each object. When the list has been exhausted, the callback will be called
+ * without an information structure and the eol parameter set to a positive
+ * value.
+ *
+ * Note that even if a single object is requested, and not the entire list,
+ * the terminating call will still be made.
+ *
+ * If an error occurs, the callback will be invoked without an information
+ * structure and eol set to a negative value..
+ *
+ * Data members in the information structures are only valid during the
+ * duration of the callback. If they are required after the callback is
+ * finished, a deep copy of the information structure must be performed.
+ *
+ * \subsection server_subsec Server Information
+ *
+ * The server can be queried about its name, the environment it's running on
+ * and the currently active global defaults. Calling
+ * pa_context_get_server_info() provides access to a pa_server_info structure
+ * containing all of these.
+ *
+ * \subsection memstat_subsec Memory Usage
+ *
+ * Statistics about memory usage can be fetched using pa_context_stat(),
+ * giving a pa_stat_info structure.
+ *
+ * \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,
+ * there are three ways to get access to them:
+ *
+ * \li By index - pa_context_get_sink_info_by_index() /
+ * pa_context_get_source_info_by_index()
+ * \li By name - pa_context_get_sink_info_by_name() /
+ * pa_context_get_source_info_by_name()
+ * \li All - pa_context_get_sink_info_list() /
+ * pa_context_get_source_info_list()
+ *
+ * All three method use the same callback and will provide a pa_sink_info or
+ * pa_source_info structure.
+ *
+ * \subsection siso_subsec Sink Inputs and Source Outputs
+ *
+ * Sink inputs and source outputs are the representations of the client ends
+ * of streams inside the server. I.e. they connect a client stream to one of
+ * the global sinks or sources.
+ *
+ * Sink inputs and source outputs only have an index to identify them. As
+ * such, there are only two ways to get information about them:
+ *
+ * \li By index - pa_context_get_sink_input_info() /
+ * pa_context_get_source_output_info()
+ * \li All - pa_context_get_sink_input_info_list() /
+ * pa_context_get_source_output_info_list()
+ *
+ * The structure returned is the pa_sink_input_info or pa_source_output_info
+ * structure.
+ *
+ * \subsection samples_subsec Samples
+ *
+ * The list of cached samples can be retrieved from the server. Three methods
+ * exist for querying the sample cache list:
+ *
+ * \li By index - pa_context_get_sample_info_by_index()
+ * \li By name - pa_context_get_sample_info_by_name()
+ * \li All - pa_context_get_sample_info_list()
+ *
+ * Note that this only retrieves information about the sample, not the sample
+ * data itself.
+ *
+ * \subsection module_subsec Driver Modules
+ *
+ * PulseAudio driver modules are identified by index and are retrieved using either
+ * pa_context_get_module_info() or pa_context_get_module_info_list(). The
+ * information structure is called pa_module_info.
+ *
+ * \subsection client_subsec Clients
+ *
+ * PulseAudio clients are also identified by index and are retrieved using
+ * either pa_context_get_client_info() or pa_context_get_client_info_list().
+ * The information structure is called pa_client_info.
+ *
+ * \section ctrl_sec Control
+ *
+ * Some parts of the server are only possible to read, but most can also be
+ * modified in different ways. Note that these changes will affect all
+ * connected clients and not just the one issuing the request.
+ *
+ * \subsection sinksrc_subsec Sinks and Sources
+ *
+ * The most common change one would want to apply to sinks and sources is to
+ * modify the volume of the audio. Identically to how sinks and sources can
+ * be queried, there are two ways of identifying them:
+ *
+ * \li By index - pa_context_set_sink_volume_by_index() /
+ * pa_context_set_source_volume_by_index()
+ * \li By name - pa_context_set_sink_volume_by_name() /
+ * pa_context_set_source_volume_by_name()
+ *
+ * It is also possible to mute a sink or source:
+ *
+ * \li By index - pa_context_set_sink_mute_by_index() /
+ * pa_context_set_source_mute_by_index()
+ * \li By name - pa_context_set_sink_mute_by_name() /
+ * pa_context_set_source_mute_by_name()
+ *
+ * \subsection siso_subsec Sink Inputs and Source Outputs
+ *
+ * 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
+ * of its associated sink input or source output, using
+ * 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:
+ *
+ * \li Sink input - pa_context_kill_sink_input()
+ * \li Source output - pa_context_kill_source_output()
+ *
+ * \subsection module_subsec Modules
+ *
+ * Server modules can be remotely loaded and unloaded using
+ * pa_context_load_module() and pa_context_unload_module().
+ *
+ * \subsection client_subsec Clients
+ *
+ * The only operation supported on clients is the possibility of kicking
+ * them off the server using pa_context_kill_client().

+ *
+ * \section overv_sec Overview
+ *
+ * The built-in main loop implementation is based on the poll() system call.
+ * It supports the functions defined in the main loop abstraction and very
+ * little else.
+ *
+ * The main loop is created using pa_mainloop_new() and destroyed using
+ * pa_mainloop_free(). To get access to the main loop abstraction,
+ * pa_mainloop_get_api() is used.
+ *
+ * \section iter_sec Iteration
+ *
+ * The main loop is designed around the concept of iterations. Each iteration
+ * consists of three steps that repeat during the application's entire
+ * lifetime:
+ *
+ * -# Prepare - Build a list of file descriptors
+ * that need to be monitored and calculate the next timeout.
+ * -# Poll - Execute the actual poll() system call.
+ * -# Dispatch - Dispatch any events that have fired.
+ *
+ * When using the main loop, the application can either execute each
+ * iteration, one at a time, using pa_mainloop_iterate(), or let the library
+ * iterate automatically using pa_mainloop_run().
+ *
+ * \section thread_sec Threads
+ *
+ * The main loop functions are designed to be thread safe, but the objects
+ * are not. What this means is that multiple main loops can be used, but only
+ * one object per thread.
+ *
+ */

+/** \mainpage
+ *
+ * \section intro_sec Introduction
+ *
+ * This document describes the client API for the PulseAudio sound
+ * server. The API comes in two flavours to accommodate different styles
+ * of applications and different needs in complexity:
+ *
+ * \li The complete but somewhat complicated to use asynchronous API
+ * \li The simplified, easy to use, but limited synchronous API
+ *
+ * All strings in PulseAudio are in the UTF-8 encoding, regardless of current
+ * locale. Some functions will filter invalid sequences from the string, some
+ * will simply fail. To ensure reliable behaviour, make sure everything you
+ * pass to the API is already in UTF-8.
+
+ * \section simple_sec Simple API
+ *
+ * Use this if you develop your program in synchronous style and just
+ * need a way to play or record data on the sound server. See
+ * \subpage simple for more details.
+ *
+ * \section async_sec Asynchronous API
+ *
+ * Use this if you develop your programs in asynchronous, event loop
+ * based style or if you want to use the advanced features of the
+ * PulseAudio API. A guide can be found in \subpage async.
+ *
+ * By using the built-in threaded main loop, it is possible to achieve a
+ * pseudo-synchronous API, which can be useful in synchronous applications
+ * where the simple API is insufficient. See the \ref async page for
+ * details.
+ *
+ * \section thread_sec Threads
+ *
+ * The PulseAudio client libraries are not designed to be directly
+ * thread-safe. They are however designed to be reentrant and
+ * threads-aware.
+ *
+ * To use the libraries in a threaded environment, you must assure that
+ * all objects are only used in one thread at a time. Normally, this means
+ * that all objects belonging to a single context must be accessed from the
+ * same thread.
+ *
+ * The included main loop implementation is also not thread safe. Take care
+ * to make sure event objects are not manipulated when any other code is
+ * using the main loop.
+ *
+ * \section error_sec Error Handling
+ *
+ * Every function should explicitly document how errors are reported to
+ * the caller. Unfortunately, currently a lot of that documentation is
+ * missing. Here is an overview of the general conventions used.
+ *
+ * The PulseAudio API indicates error conditions by returning a negative
+ * integer value or a NULL pointer. On success, zero or a positive integer
+ * value or a valid pointer is returned.
+ *
+ * Functions of the \ref simple generally return -1 or NULL on failure and
+ * can optionally store an error code (see ::pa_error_code) using a pointer
+ * argument.
+ *
+ * Functions of the \ref async return an negative error code or NULL on
+ * failure (see ::pa_error_code). In the later case, pa_context_errno()
+ * can be used to obtain the error code of the last failed operation.
+ *
+ * An error code can be turned into a human readable message using
+ * pa_strerror().
+ *
+ * \section pkgconfig pkg-config
+ *
+ * The PulseAudio libraries provide pkg-config snippets for the different
+ * modules:
+ *
+ * \li libpulse - The asynchronous API and the internal main loop implementation.
+ * \li libpulse-mainloop-glib - GLIB 2.x main loop bindings.
+ * \li libpulse-simple - The simple PulseAudio API.

+/** \page sample Sample Format Specifications
+ *
+ * \section overv_sec Overview
+ *
+ * PulseAudio is capable of handling a multitude of sample formats, rates
+ * and channels, transparently converting and mixing them as needed.
+ *
+ * \section format_sec Sample Format
+ *
+ * PulseAudio supports the following sample formats:
+ *
+ * \li PA_SAMPLE_U8 - Unsigned 8 bit integer PCM.
+ * \li PA_SAMPLE_S16LE - Signed 16 integer bit PCM, little endian.
+ * \li PA_SAMPLE_S16BE - Signed 16 integer bit PCM, big endian.
+ * \li PA_SAMPLE_FLOAT32LE - 32 bit IEEE floating point PCM, little endian.
+ * \li PA_SAMPLE_FLOAT32BE - 32 bit IEEE floating point PCM, big endian.
+ * \li PA_SAMPLE_ALAW - 8 bit a-Law.
+ * \li PA_SAMPLE_ULAW - 8 bit mu-Law.
+ * \li PA_SAMPLE_S32LE - Signed 32 bit integer PCM, little endian.
+ * \li PA_SAMPLE_S32BE - Signed 32 bit integer PCM, big endian.
+ * \li PA_SAMPLE_S24LE - Signed 24 bit integer PCM packed, little endian.
+ * \li PA_SAMPLE_S24BE - Signed 24 bit integer PCM packed, big endian.
+ * \li PA_SAMPLE_S24_32LE - Signed 24 bit integer PCM in LSB of 32 bit words, little endian.
+ * \li PA_SAMPLE_S24_32BE - Signed 24 bit integer PCM in LSB of 32 bit words, big endian.
+ *
+ * The floating point sample formats have the range from -1.0 to 1.0.
+ *
+ * The sample formats that are sensitive to endianness have convenience
+ * macros for native endian (NE), and reverse endian (RE).
+ *
+ * \section rate_sec Sample Rates
+ *
+ * PulseAudio supports any sample rate between 1 Hz and 192000 Hz. There is no
+ * point trying to exceed the sample rate of the output device though as the
+ * signal will only get downsampled, consuming CPU on the machine running the
+ * server.
+ *
+ * \section chan_sec Channels
+ *
+ * PulseAudio supports up to 32 individual channels. The order of the
+ * channels is up to the application, but they must be continuous. To map
+ * channels to speakers, see \ref channelmap.
+ *
+ * \section calc_sec Calculations
+ *
+ * The PulseAudio library contains a number of convenience functions to do
+ * calculations on sample formats:
+ *
+ * \li pa_bytes_per_second() - The number of bytes one second of audio will
+ * take given a sample format.
+ * \li pa_frame_size() - The size, in bytes, of one frame (i.e. one set of
+ * samples, one for each channel).
+ * \li pa_sample_size() - The size, in bytes, of one sample.
+ * \li pa_bytes_to_usec() - Calculate the time it would take to play a buffer
+ * of a certain size.
+ *
+ * \section util_sec Convenience Functions
+ *
+ * The library also contains a couple of other convenience functions:
+ *
+ * \li pa_sample_spec_valid() - Tests if a sample format specification is
+ * valid.
+ * \li pa_sample_spec_equal() - Tests if the sample format specifications are
+ * identical.
+ * \li pa_sample_format_to_string() - Return a textual description of a
+ * sample format.
+ * \li pa_parse_sample_format() - Parse a text string into a sample format.
+ * \li pa_sample_spec_snprint() - Create a textual description of a complete
+ * sample format specification.
+ * \li pa_bytes_snprint() - Pretty print a byte value (e.g. 2.5 MiB).

+ * The sample cache provides a simple way of overcoming high network latencies

+ * playing it needs to be sent.
+ *
+ * \section create_sec Creation
+ *
+ * To create a sample, the normal stream API is used (see \ref streams). The
+ * function pa_stream_connect_upload() will make sure the stream is stored as
+ * a sample on the server.
+ *
+ * To complete the upload, pa_stream_finish_upload() is called and the sample
+ * will receive the same name as the stream. If the upload should be aborted,
+ * simply call pa_stream_disconnect().
+ *
+ * \section play_sec Playing samples
+ *
+ * To play back a sample, simply call pa_context_play_sample():
+ *
+ * \code
+ * pa_operation *o;
+ *
+ * o = pa_context_play_sample(my_context,
+ * "sample2", // Name of my sample

+ *
+ * \section overv_sec Overview
+ *
+ * The simple API is designed for applications with very basic sound
+ * playback or capture needs. It can only support a single stream per
+ * connection and has no support for handling of complex features like
+ * events, channel mappings and volume control. It is, however, very simple
+ * to use and quite sufficient for many programs.
+ *
+ * \section conn_sec Connecting
+ *
+ * The first step before using the sound system is to connect to the
+ * server. This is normally done this way:
+ *
+ * \code
+ * pa_simple *s;
+ * pa_sample_spec ss;
+ *
+ * ss.format = PA_SAMPLE_S16NE;
+ * ss.channels = 2;
+ * ss.rate = 44100;
+ *
+ * s = pa_simple_new(NULL, // Use the default server.
+ * "Fooapp", // Our application's name.
+ * PA_STREAM_PLAYBACK,
+ * NULL, // Use the default device.
+ * "Music", // Description of our stream.
+ * &ss, // Our sample format.
+ * NULL, // Use default channel map
+ * NULL, // Use default buffering attributes.
+ * NULL, // Ignore error code.
+ * );
+ * \endcode
+ *
+ * At this point a connected object is returned, or NULL if there was a
+ * problem connecting.
+ *
+ * \section transfer_sec Transferring data
+ *
+ * Once the connection is established to the server, data can start flowing.
+ * Using the connection is very similar to the normal read() and write()
+ * system calls. The main difference is that they're called pa_simple_read()
+ * and pa_simple_write(). Note that these operations always block.
+ *
+ * \section ctrl_sec Buffer control
+ *
+ * If a playback stream is used then a few other operations are available:
+ *
+ * \li pa_simple_drain() - Will wait for all sent data to finish playing.
+ * \li pa_simple_flush() - Will throw away all data currently in buffers.
+ * \li pa_simple_get_latency() - Will return the total latency of
+ * the playback pipeline.
+ *
+ * \section cleanup_sec Cleanup
+ *
+ * Once playback or capture is complete, the connection should be closed
+ * and resources freed. This is done through:
+ *
+ * \code
+ * pa_simple_free(s);
+ * \endcode

+/** \page streams Audio Streams
+ *
+ * \section overv_sec Overview
+ *
+ * Audio streams form the central functionality of the sound server. Data is
+ * routed, converted and mixed from several sources before it is passed along
+ * to a final output. Currently, there are three forms of audio streams:
+ *
+ * \li Playback streams - Data flows from the client to the server.
+ * \li Record streams - Data flows from the server to the client.
+ * \li Upload streams - Similar to playback streams, but the data is stored in
+ * the sample cache. See \ref scache for more information
+ * about controlling the sample cache.
+ *
+ * \section create_sec Creating
+ *
+ * To access a stream, a pa_stream object must be created using
+ * pa_stream_new(). At this point the audio sample format and mapping of
+ * channels must be specified. See \ref sample and \ref channelmap for more
+ * information about those structures.
+ *
+ * This first step will only create a client-side object, representing the
+ * stream. To use the stream, a server-side object must be created and
+ * associated with the local object. Depending on which type of stream is
+ * desired, a different function is needed:
+ *
+ * \li Playback stream - pa_stream_connect_playback()
+ * \li Record stream - pa_stream_connect_record()
+ * \li Upload stream - pa_stream_connect_upload() (see \ref scache)
+ *
+ * Similar to how connections are done in contexts, connecting a stream will
+ * not generate a pa_operation object. Also like contexts, the application
+ * should register a state change callback, using
+ * pa_stream_set_state_callback(), and wait for the stream to enter an active
+ * state.
+ *
+ * \subsection bufattr_subsec Buffer Attributes
+ *
+ * Playback and record streams always have a server-side buffer as
+ * part of the data flow. The size of this buffer needs to be chosen
+ * in a compromise between low latency and sensitivity for buffer
+ * overflows/underruns.
+ *
+ * The buffer metrics may be controlled by the application. They are
+ * described with a pa_buffer_attr structure which contains a number
+ * of fields:
+ *
+ * \li maxlength - The absolute maximum number of bytes that can be
+ * stored in the buffer. If this value is exceeded
+ * then data will be lost. It is recommended to pass
+ * (uint32_t) -1 here which will cause the server to
+ * fill in the maximum possible value.
+ *
+ * \li tlength - The target fill level of the playback buffer. The
+ * server will only send requests for more data as long
+ * as the buffer has less than this number of bytes of
+ * data. If you pass (uint32_t) -1 (which is
+ * recommended) here the server will choose the longest
+ * target buffer fill level possible to minimize the
+ * number of necessary wakeups and maximize drop-out
+ * safety. This can exceed 2s of buffering. For
+ * low-latency applications or applications where
+ * latency matters you should pass a proper value here.
+ *
+ * \li prebuf - Number of bytes that need to be in the buffer before
+ * playback will commence. Start of playback can be
+ * forced using pa_stream_trigger() even though the
+ * prebuffer size hasn't been reached. If a buffer
+ * underrun occurs, this prebuffering will be again
+ * enabled. If the playback shall never stop in case of a
+ * buffer underrun, this value should be set to 0. In
+ * that case the read index of the output buffer
+ * overtakes the write index, and hence the fill level of
+ * the buffer is negative. If you pass (uint32_t) -1 here
+ * (which is recommended) the server will choose the same
+ * value as tlength here.
+ *
+ * \li minreq - Minimum free number of the bytes in the playback
+ * buffer before the server will request more data. It is
+ * recommended to fill in (uint32_t) -1 here. This value
+ * influences how much time the sound server has to move
+ * data from the per-stream server-side playback buffer
+ * to the hardware playback buffer.
+ *
+ * \li fragsize - Maximum number of bytes that the server will push in
+ * one chunk for record streams. If you pass (uint32_t)
+ * -1 (which is recommended) here, the server will
+ * choose the longest fragment setting possible to
+ * minimize the number of necessary wakeups and
+ * maximize drop-out safety. This can exceed 2s of
+ * buffering. For low-latency applications or
+ * applications where latency matters you should pass a
+ * proper value here.
+ *
+ * If PA_STREAM_ADJUST_LATENCY is set, then the tlength/fragsize
+ * parameters will be interpreted slightly differently than described
+ * above when passed to pa_stream_connect_record() and
+ * pa_stream_connect_playback(): the overall latency that is comprised
+ * of both the server side playback buffer length, the hardware
+ * playback buffer length and additional latencies will be adjusted in
+ * a way that it matches tlength resp. fragsize. Set
+ * PA_STREAM_ADJUST_LATENCY if you want to control the overall
+ * playback latency for your stream. Unset it if you want to control
+ * only the latency induced by the server-side, rewritable playback
+ * buffer. The server will try to fulfill the clients latency requests
+ * as good as possible. However if the underlying hardware cannot
+ * change the hardware buffer length or only in a limited range, the
+ * actually resulting latency might be different from what the client
+ * requested. Thus, for synchronization clients always need to check
+ * the actual measured latency via pa_stream_get_latency() or a
+ * similar call, and not make any assumptions. about the latency
+ * available. The function pa_stream_get_buffer_attr() will always
+ * return the actual size of the server-side per-stream buffer in
+ * tlength/fragsize, regardless whether PA_STREAM_ADJUST_LATENCY is
+ * set or not.
+ *
+ * The server-side per-stream playback buffers are indexed by a write and a read
+ * index. The application writes to the write index and the sound
+ * device reads from the read index. The read index is increased
+ * monotonically, while the write index may be freely controlled by
+ * the application. Subtracting the read index from the write index
+ * will give you the current fill level of the buffer. The read/write
+ * indexes are 64bit values and measured in bytes, they will never
+ * wrap. The current read/write index may be queried using
+ * pa_stream_get_timing_info() (see below for more information). In
+ * case of a buffer underrun the read index is equal or larger than
+ * the write index. Unless the prebuf value is 0, PulseAudio will
+ * temporarily pause playback in such a case, and wait until the
+ * buffer is filled up to prebuf bytes again. If prebuf is 0, the
+ * read index may be larger than the write index, in which case
+ * silence is played. If the application writes data to indexes lower
+ * than the read index, the data is immediately lost.
+ *
+ * \section transfer_sec Transferring Data
+ *
+ * Once the stream is up, data can start flowing between the client and the
+ * server. Two different access models can be used to transfer the data:
+ *
+ * \li Asynchronous - The application register a callback using
+ * pa_stream_set_write_callback() and
+ * pa_stream_set_read_callback() to receive notifications
+ * that data can either be written or read.
+ * \li Polled - Query the library for available data/space using
+ * pa_stream_writable_size() and pa_stream_readable_size() and
+ * transfer data as needed. The sizes are stored locally, in the
+ * client end, so there is no delay when reading them.
+ *
+ * It is also possible to mix the two models freely.
+ *
+ * Once there is data/space available, it can be transferred using either
+ * pa_stream_write() for playback, or pa_stream_peek() / pa_stream_drop() for
+ * record. Make sure you do not overflow the playback buffers as data will be
+ * dropped.
+ *
+ * \section bufctl_sec Buffer Control
+ *
+ * The transfer buffers can be controlled through a number of operations:
+ *
+ * \li pa_stream_cork() - Start or stop the playback or recording.
+ * \li pa_stream_trigger() - Start playback immediately and do not wait for
+ * the buffer to fill up to the set trigger level.
+ * \li pa_stream_prebuf() - Reenable the playback trigger level.
+ * \li pa_stream_drain() - Wait for the playback buffer to go empty. Will
+ * return a pa_operation object that will indicate when
+ * the buffer is completely drained.
+ * \li pa_stream_flush() - Drop all data from the playback buffer and do not
+ * wait for it to finish playing.
+ *
+ * \section seek_modes Seeking in the Playback Buffer
+ *
+ * A client application may freely seek in the playback buffer. To
+ * accomplish that the pa_stream_write() function takes a seek mode
+ * and an offset argument. The seek mode is one of:
+ *
+ * \li PA_SEEK_RELATIVE - seek relative to the current write index
+ * \li PA_SEEK_ABSOLUTE - seek relative to the beginning of the playback buffer, (i.e. the first that was ever played in the stream)
+ * \li PA_SEEK_RELATIVE_ON_READ - seek relative to the current read index. Use this to write data to the output buffer that should be played as soon as possible
+ * \li PA_SEEK_RELATIVE_END - seek relative to the last byte ever written.
+ *
+ * If an application just wants to append some data to the output
+ * buffer, PA_SEEK_RELATIVE and an offset of 0 should be used.
+ *
+ * After a call to pa_stream_write() the write index will be left at
+ * the position right after the last byte of the written data.
+ *
+ * \section latency_sec Latency
+ *
+ * A major problem with networked audio is the increased latency caused by
+ * the network. To remedy this, PulseAudio supports an advanced system of
+ * monitoring the current latency.
+ *
+ * To get the raw data needed to calculate latencies, call
+ * pa_stream_get_timing_info(). This will give you a pa_timing_info
+ * structure that contains everything that is known about the server
+ * side buffer transport delays and the backend active in the
+ * server. (Besides other things it contains the write and read index
+ * values mentioned above.)
+ *
+ * This structure is updated every time a
+ * pa_stream_update_timing_info() operation is executed. (i.e. before
+ * the first call to this function the timing information structure is
+ * not available!) Since it is a lot of work to keep this structure
+ * up-to-date manually, PulseAudio can do that automatically for you:
+ * if PA_STREAM_AUTO_TIMING_UPDATE is passed when connecting the
+ * stream PulseAudio will automatically update the structure every
+ * 100ms and every time a function is called that might invalidate the
+ * previously known timing data (such as pa_stream_write() or
+ * pa_stream_flush()). Please note however, that there always is a
+ * short time window when the data in the timing information structure
+ * is out-of-date. PulseAudio tries to mark these situations by
+ * setting the write_index_corrupt and read_index_corrupt fields
+ * accordingly.
+ *
+ * The raw timing data in the pa_timing_info structure is usually hard
+ * to deal with. Therefore a simpler interface is available:
+ * you can call pa_stream_get_time() or pa_stream_get_latency(). The
+ * former will return the current playback time of the hardware since
+ * the stream has been started. The latter returns the overall time a sample
+ * that you write now takes to be played by the hardware. These two
+ * functions base their calculations on the same data that is returned
+ * by pa_stream_get_timing_info(). Hence the same rules for keeping
+ * the timing data up-to-date apply here. In case the write or read
+ * index is corrupted, these two functions will fail with
+ * -PA_ERR_NODATA set.
+ *
+ * Since updating the timing info structure usually requires a full
+ * network round trip and some applications monitor the timing very
+ * often PulseAudio offers a timing interpolation system. If
+ * PA_STREAM_INTERPOLATE_TIMING is passed when connecting the stream,
+ * pa_stream_get_time() and pa_stream_get_latency() will try to
+ * interpolate the current playback time/latency by estimating the
+ * number of samples that have been played back by the hardware since
+ * the last regular timing update. It is especially useful to combine
+ * this option with PA_STREAM_AUTO_TIMING_UPDATE, which will enable
+ * you to monitor the current playback time/latency very precisely and
+ * very frequently without requiring a network round trip every time.
+ *
+ * \section flow_sec Overflow and underflow
+ *
+ * Even with the best precautions, buffers will sometime over - or
+ * underflow. To handle this gracefully, the application can be
+ * notified when this happens. Callbacks are registered using
+ * pa_stream_set_overflow_callback() and
+ * pa_stream_set_underflow_callback().
+ *
+ * \section sync_streams Synchronizing Multiple Playback Streams
+ *
+ * PulseAudio allows applications to fully synchronize multiple
+ * playback streams that are connected to the same output device. That
+ * means the streams will always be played back sample-by-sample
+ * synchronously. If stream operations like pa_stream_cork() are
+ * issued on one of the synchronized streams, they are simultaneously
+ * issued on the others.
+ *
+ * To synchronize a stream to another, just pass the "master" stream
+ * as last argument to pa_stream_connect_playback(). To make sure that
+ * the freshly created stream doesn't start playback right-away, make
+ * sure to pass PA_STREAM_START_CORKED and -- after all streams have
+ * been created -- uncork them all with a single call to
+ * pa_stream_cork() for the master stream.
+ *
+ * To make sure that a particular stream doesn't stop to play when a
+ * server side buffer underrun happens on it while the other
+ * synchronized streams continue playing and hence deviate, you need to
+ * pass a "prebuf" pa_buffer_attr of 0 when connecting it.
+ *
+ * \section disc_sec Disconnecting
+ *
+ * When a stream has served is purpose it must be disconnected with
+ * pa_stream_disconnect(). If you only unreference it, then it will live on
+ * and eat resources both locally and on the server until you disconnect the
+ * context.

+/** \page threaded_mainloop Threaded Main Loop
+ *
+ * \section overv_sec Overview
+ *
+ * The threaded main loop implementation is a special version of the primary
+ * main loop implementation (see \ref mainloop). For the basic design, see
+ * its documentation.
+ *
+ * The added feature in the threaded main loop is that it spawns a new thread
+ * that runs the real main loop. This allows a synchronous application to use
+ * the asynchronous API without risking to stall the PulseAudio library.
+ *
+ * \section creat_sec Creation
+ *
+ * A pa_threaded_mainloop object is created using pa_threaded_mainloop_new().
+ * This will only allocate the required structures though, so to use it the
+ * thread must also be started. This is done through
+ * pa_threaded_mainloop_start(), after which you can start using the main loop.
+ *
+ * \section destr_sec Destruction
+ *
+ * When the PulseAudio connection has been terminated, the thread must be
+ * stopped and the resources freed. Stopping the thread is done using
+ * pa_threaded_mainloop_stop(), which must be called without the lock (see
+ * below) held. When that function returns, the thread is stopped and the
+ * pa_threaded_mainloop object can be freed using pa_threaded_mainloop_free().
+ *
+ * \section lock_sec Locking
+ *
+ * Since the PulseAudio API doesn't allow concurrent accesses to objects,
+ * a locking scheme must be used to guarantee safe usage. The threaded main
+ * loop API provides such a scheme through the functions
+ * pa_threaded_mainloop_lock() and pa_threaded_mainloop_unlock().
+ *
+ * The lock is recursive, so it's safe to use it multiple times from the same
+ * thread. Just make sure you call pa_threaded_mainloop_unlock() the same
+ * number of times you called pa_threaded_mainloop_lock().
+ *
+ * The lock needs to be held whenever you call any PulseAudio function that
+ * uses an object associated with this main loop. Make sure you do not hold
+ * on to the lock more than necessary though, as the threaded main loop stops
+ * while the lock is held.
+ *
+ * Example:
+ *
+ * \code
+ * void my_check_stream_func(pa_threaded_mainloop *m, pa_stream *s) {
+ * pa_stream_state_t state;
+ *
+ * pa_threaded_mainloop_lock(m);
+ *
+ * state = pa_stream_get_state(s);
+ *
+ * pa_threaded_mainloop_unlock(m);
+ *
+ * if (state == PA_STREAM_READY)
+ * printf("Stream is ready!");
+ * else
+ * printf("Stream is not ready!");
+ * }
+ * \endcode
+ *
+ * \section cb_sec Callbacks
+ *
+ * Callbacks in PulseAudio are asynchronous, so they require extra care when
+ * using them together with a threaded main loop.
+ *
+ * The easiest way to turn the callback based operations into synchronous
+ * ones, is to simply wait for the callback to be called and continue from
+ * there. This is the approach chosen in PulseAudio's threaded API.
+ *
+ * \subsection basic_subsec Basic callbacks
+ *
+ * For the basic case, where all that is required is to wait for the callback
+ * to be invoked, the code should look something like this:
+ *
+ * Example:
+ *
+ * \code
+ * static void my_drain_callback(pa_stream *s, int success, void *userdata) {
+ * pa_threaded_mainloop *m;
+ *
+ * m = userdata;
+ * assert(m);
+ *
+ * pa_threaded_mainloop_signal(m, 0);
+ * }
+ *
+ * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) {
+ * pa_operation *o;
+ *
+ * pa_threaded_mainloop_lock(m);
+ *
+ * o = pa_stream_drain(s, my_drain_callback, m);
+ * assert(o);
+ *
+ * while (pa_operation_get_state(o) == PA_OPERATION_RUNNING)
+ * pa_threaded_mainloop_wait(m);
+ *
+ * pa_operation_unref(o);
+ *
+ * pa_threaded_mainloop_unlock(m);
+ * }
+ * \endcode
+ *
+ * The main function, my_drain_stream_func(), will wait for the callback to
+ * be called using pa_threaded_mainloop_wait().
+ *
+ * If your application is multi-threaded, then this waiting must be
+ * done inside a while loop. The reason for this is that multiple
+ * threads might be using pa_threaded_mainloop_wait() at the same
+ * time. Each thread must therefore verify that it was its callback
+ * that was invoked. Also the underlying OS synchronization primitives
+ * are usually not free of spurious wake-ups, so a
+ * pa_threaded_mainloop_wait() must be called within a loop even if
+ * you have only one thread waiting.
+ *
+ * The callback, my_drain_callback(), indicates to the main function that it
+ * has been called using pa_threaded_mainloop_signal().
+ *
+ * As you can see, pa_threaded_mainloop_wait() may only be called with
+ * the lock held. The same thing is true for pa_threaded_mainloop_signal(),
+ * but as the lock is held before the callback is invoked, you do not have to
+ * deal with that.
+ *
+ * The functions will not dead lock because the wait function will release
+ * the lock before waiting and then regrab it once it has been signalled.
+ * For those of you familiar with threads, the behaviour is that of a
+ * condition variable.
+ *
+ * \subsection data_subsec Data callbacks
+ *
+ * For many callbacks, simply knowing that they have been called is
+ * insufficient. The callback also receives some data that is desired. To
+ * access this data safely, we must extend our example a bit:
+ *
+ * \code
+ * static int *drain_result;
+ *
+ * static void my_drain_callback(pa_stream*s, int success, void *userdata) {
+ * pa_threaded_mainloop *m;
+ *
+ * m = userdata;
+ * assert(m);
+ *
+ * drain_result = &success;
+ *
+ * pa_threaded_mainloop_signal(m, 1);
+ * }
+ *
+ * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) {
+ * pa_operation *o;
+ *
+ * pa_threaded_mainloop_lock(m);
+ *
+ * o = pa_stream_drain(s, my_drain_callback, m);
+ * assert(o);
+ *
+ * while (pa_operation_get_state(o) == PA_OPERATION_RUNNING)
+ * pa_threaded_mainloop_wait(m);
+ *
+ * pa_operation_unref(o);
+ *
+ * if (*drain_result)
+ * printf("Success!");
+ * else
+ * printf("Bitter defeat...");
+ *
+ * pa_threaded_mainloop_accept(m);
+ *
+ * pa_threaded_mainloop_unlock(m);
+ * }
+ * \endcode
+ *
+ * The example is a bit silly as it would probably have been easier to just
+ * copy the contents of success, but for larger data structures this can be
+ * wasteful.
+ *
+ * The difference here compared to the basic callback is the value 1 passed
+ * to pa_threaded_mainloop_signal() and the call to
+ * pa_threaded_mainloop_accept(). What will happen is that
+ * pa_threaded_mainloop_signal() will signal the main function and then wait.
+ * The main function is then free to use the data in the callback until
+ * pa_threaded_mainloop_accept() is called, which will allow the callback
+ * to continue.
+ *
+ * Note that pa_threaded_mainloop_accept() must be called some time between
+ * exiting the while loop and unlocking the main loop! Failure to do so will
+ * result in a race condition. I.e. it is not ok to release the lock and
+ * regrab it before calling pa_threaded_mainloop_accept().
+ *
+ * \subsection async_subsec Asynchronous callbacks
+ *
+ * PulseAudio also has callbacks that are completely asynchronous, meaning
+ * that they can be called at any time. The threaded main loop API provides
+ * the locking mechanism to handle concurrent accesses, but nothing else.
+ * Applications will have to handle communication from the callback to the
+ * main program through its own mechanisms.
+ *
+ * The callbacks that are completely asynchronous are:
+ *
+ * \li State callbacks for contexts, streams, etc.
+ * \li Subscription notifications

+/** \page volume Volume Control
+ *
+ * \section overv_sec Overview
+ *
+ * Sinks, sources, sink inputs and samples can all have their own volumes.
+ * To deal with these, The PulseAudio library contains a number of functions
+ * that ease handling.
+ *
+ * The basic volume type in PulseAudio is the \ref pa_volume_t type. Most of
+ * the time, applications will use the aggregated pa_cvolume structure that
+ * can store the volume of all channels at once.
+ *
+ * Volumes commonly span between muted (0%), and normal (100%). It is possible
+ * to set volumes to higher than 100%, but clipping might occur.
+ *
+ * \section calc_sec Calculations
+ *
+ * The volumes in PulseAudio are logarithmic in nature and applications
+ * shouldn't perform calculations with them directly. Instead, they should
+ * be converted to and from either dB or a linear scale:
+ *
+ * \li dB - pa_sw_volume_from_dB() / pa_sw_volume_to_dB()
+ * \li Linear - pa_sw_volume_from_linear() / pa_sw_volume_to_linear()
+ *
+ * For simple multiplication, pa_sw_volume_multiply() and
+ * pa_sw_cvolume_multiply() can be used.
+ *
+ * Calculations can only be reliably performed on software volumes
+ * as it is commonly unknown what scale hardware volumes relate to.
+ *
+ * The functions described above are only valid when used with
+ * software volumes. Hence it is usually a better idea to treat all
+ * volume values as opaque with a range from PA_VOLUME_MUTED (0%) to
+ * PA_VOLUME_NORM (100%) and to refrain from any calculations with
+ * them.
+ *
+ * \section conv_sec Convenience Functions
+ *
+ * To handle the pa_cvolume structure, the PulseAudio library provides a
+ * number of convenience functions:
+ *
+ * \li pa_cvolume_valid() - Tests if a pa_cvolume structure is valid.
+ * \li pa_cvolume_equal() - Tests if two pa_cvolume structures are identical.
+ * \li pa_cvolume_channels_equal_to() - Tests if all channels of a pa_cvolume
+ * structure have a given volume.
+ * \li pa_cvolume_is_muted() - Tests if all channels of a pa_cvolume
+ * structure are muted.
+ * \li pa_cvolume_is_norm() - Tests if all channels of a pa_cvolume structure
+ * are at a normal volume.
+ * \li pa_cvolume_set() - Set the first n channels of a pa_cvolume structure to
+ * a certain volume.
+ * \li pa_cvolume_reset() - Set the first n channels of a pa_cvolume structure
+ * to a normal volume.
+ * \li pa_cvolume_mute() - Set the first n channels of a pa_cvolume structure
+ * to a muted volume.
+ * \li pa_cvolume_avg() - Return the average volume of all channels.
+ * \li pa_cvolume_snprint() - Pretty print a pa_cvolume structure.
