+ *
+ * \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 API 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 API 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 logging_sec Logging
+ *
+ * You can configure different logging parameters for the PulseAudio client
+ * libraries. The following environment variables are recognized:
+ *
+ *  - `PULSE_LOG`: Maximum log level required. Bigger values result in a
+ *     more verbose logging output. The following values are recognized:
+ *     + `0`: Error messages
+ *     + `1`: Warning messages
+ *     + `2`: Notice messages
+ *     + `3`: Info messages
+ *     + `4`: Debug messages
+ *  - `PULSE_LOG_SYSLOG`: If defined, force all client libraries to log
+ *     their output using the syslog(3) mechanism. Default behavior is to
+ *     log all output to stderr.
+ *  - `PULSE_LOG_JOURNAL`: If defined, force all client libraries to log
+ *     their output using the systemd journal. If both `PULSE_LOG_JOURNAL`
+ *     and `PULSE_LOG_SYSLOG` are defined, logging to the systemd journal
+ *     takes a higher precedence. Each message originating library file name
+ *     and function are included by default through the journal fields
+ *     `CODE_FILE`, `CODE_FUNC`, and `CODE_LINE`. Any backtrace attached to
+ *     the logging message is sent through the PulseAudio-specific journal
+ *     field `PULSE_BACKTRACE`. This environment variable has no effect if
+ *     PulseAudio was compiled without systemd journal support.
+ *  - `PULSE_LOG_COLORS`: If defined, enables colored logging output.
+ *  - `PULSE_LOG_TIME`: If defined, include timestamps with each message.
+ *  - `PULSE_LOG_FILE`: If defined, include each message originating file
+ *     name.
+ *  - `PULSE_LOG_META`: If defined, include each message originating file
+ *     name and path relative to the PulseAudio source tree root.
+ *  - `PULSE_LOG_LEVEL`: If defined, include a log level prefix with each
+ *     message. Respectively, the prefixes "E", "W", "N", "I", "D" stands
+ *     for Error, Warning, Notice, Info, and Debugging.
+ *  - `PULSE_LOG_BACKTRACE`: Number of functions to display in the backtrace.
+ *     If this variable is not defined, or has a value of zero, no backtrace
+ *     is shown.
+ *  - `PULSE_LOG_BACKTRACE_SKIP`: Number of backtrace levels to skip, from
+ *     the function printing the log message downwards.
+ *  - `PULSE_LOG_NO_RATE_LIMIT`: If defined, do not rate limit the logging
+ *     output. Rate limiting skips certain log messages when their frequency
+ *     is considered too high.
+ *
+ * \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.
