31 * XTOOLKIT This will be part of an Xt program.
|
|
|
32 *
|
|
|
33 * XTEVENTS The playing will be supervised asynchronously by the Xt event
|

34 * loop. If not set, playing will be completed within the call
|
|
|
35 * to play_file etc.
|
|
|
36 *
|
|
|
37 * ROBUST_PLAY Causes errors in nas to be caught. This means that the
|
|
|
38 * program will attempt not to die if the nas server does.
|
|
|
39 *
|
|
|
40 * CACHE_SOUNDS Causes the sounds to be played in buckets in the NAS
|
|
|
41 * server. They are named by their comment field, or if that is
|
|
|
42 * empty by the filename, or for play_sound_data by a name made up
|
|
|
43 * from the sample itself.

|
|
|
47 * 10/8/94, rjc Changed names from netaudio to nas
|
|
|
48 * Added back asynchronous play if nas library has
|
|
|
49 * correct error facilities.
|
|
|
50 * 4/11/94, rjc Added wait_for_sounds to be called when user wants to

51 * be sure all play has finished.
