42 * CACHE_SOUNDS Causes the sounds to be played in buckets in the NAS

|
44 * empty by the filename, or for play_sound_data by a name made up

48 /* CHANGES:
|
|
|
49 * 10/8/94, rjc Changed names from netaudio to nas
|
|
|
50 * Added back asynchronous play if nas library has
|
|
|
51 * correct error facilities.
|
|
|
52 * 4/11/94, rjc Added wait_for_sounds to be called when user wants to
|
|
|
53 * be sure all play has finished.
|
|
|
54 * 1998-10-01 rlt Added support for WAVE files.
|
|
1097
|
55 * 2002-10-16 Jon Trulson modifed this to work with NAS releases
|
|
|
56 * 1.5f and higher. We were using the private variable
|
|
|
57 * SoundFileInfo that doesn't exist anymore. But preserve
|
|
|
58 * backward compatibility. This will not work for some
|
|
|
59 * versions of NAS around 1.5b to 1.5f or so. Known to
|
|
|
60 * work on 1.2p5 and 1.6.
