   6  * wwviaudio - realtime playback and mixing of 16 bit signed PCM audio data.
   7  *
   8  * wwviaudio provides a set of functions for realtime playback and mixing
   9  * of audio samples, e.g. music, sound effects, etc. as in a video game.
  10  *
  11  * Example:
  12  *
  13  *      something along these lines:
  14  *
  15  *      if (wwviaudio_initialize_portaudio() != 0)
  16  *              bail_out_and_die();
  17  *
  18  *      You would probably use #defines or enums rather than bare ints...
  19  *      wwviaudio_read_ogg_clip(1, "mysound1.ogg");
  20  *      wwviaudio_read_ogg_clip(2, "mysound2.ogg");
  21  *      wwviaudio_read_ogg_clip(3, "mysound3.ogg");
  22  *      wwviaudio_read_ogg_clip(4, "mymusic.ogg");
  23  *
  24  *       ...
  25  *
  26  *      wwviaudio_play_music(4); <-- begins playing music in background, returns immediately
  27  *
  28  *      while (program isn't done) {
  29  *              do_stuff();
  30  *              if (something happened)
  31  *                      wwviaudio_add_sound(1);
  32  *              if (something else happened)
  33  *                      wwviaudio_add_sound(2);
  34  *              time_passes();
  35  *      }
  36  *
  37  *      wwviaudio_cancel_all_sounds();
  38  *      wwviaduio_stop_portaudio();
