  * 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.
