Suppose you're playing an Allegro game under Linux console: how do you modify

Normally, you set the golbal volume once, and then leave it at that. I
don't think most users regularly change the global volume.
However, I still don't think that Allegro should play with it. After
all, the user may be running some other sound producing application in
the background (an MP3/ogg player for example). We don't want to be rude
and change the volume for that player too.
However I guess your proposition makes more sense with windowing systems
(Windows, BeOS, QNX, KDE) where you are always only two keystrokes away from
the global sound mixer.
Good point.
So I think we could try to have both functionalities:
- set_volume() with a more complete documentation explaining its drawbacks,
- set_local_volume() which doesn't touch the global mixer.
How about:
set_volume() - doesn't touch the global volume (ie: the "right" way)
set_global_volume() - changes the global volume, for users that really
need it.
How do you see then the relationship between set_local_volume() and
voice_set_volume() ?
final volume = global * local
