33 * XTOOLKIT This will be part of an Xt program.
|
|

34 *
|

35 * XTEVENTS The playing will be supervised asynchronously by the Xt event

37 * to play_file etc.

39 * ROBUST_PLAY Causes errors in nas to be caught. This means that the
|
|
|
40 * program will attempt not to die if the nas server does.
|
|
|
41 *
|
|
|
42 * CACHE_SOUNDS Causes the sounds to be played in buckets in the NAS
|
|
|
43 * server. They are named by their comment field, or if that is
|
|
|
44 * empty by the filename, or for play_sound_data by a name made up
|
|
|
45 * from the sample itself.

|
|
|
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.
