 * Main loop abstraction layer. Both the PulseAudio core and the
 * PulseAudio client library use a main loop abstraction layer. Due to
 * this it is possible to embed PulseAudio into other
 * applications easily. Two main loop implementations are
 * currently available:
 * \li A minimal implementation based on the C library's poll() function (See \ref mainloop.h)
 * \li A wrapper around the GLIB main loop. Use this to embed PulseAudio into your GLIB/GTK+/GNOME programs (See \ref glib-mainloop.h)
 *
 * The structure pa_mainloop_api is used as vtable for the main loop abstraction.
 *
 * This mainloop abstraction layer has no direct support for UNIX signals. Generic, mainloop implementation agnostic support is available through \ref mainloop-signal.h.
