Unfortunately there's not much more than the events atm :(

No. The sound() function will select proper sound handle for the action
and parameters and pass it to actual sound making plugin. The handle
could be filename.

something like

void sound (pplayer, action, data1, data2) {
  Sound  snd_handle = get_sound_handle (pplayer, action, data1, data2);
  sound_play (snd_handle);
}

The get_sound_handle() selects sound handle based on config file and
combination of parameters.

The way I want it to work (and the direction in which I am developing)
is to resemble X resources.

sound_play() is a stub function for plugin's play function. It might mix
the wave with others, spool it to esd, whatever it needs to do the
output

As I have written in other mail, atm I am not interested in actual
implementation of sound output. I want to do it through plugins,
however. So there could be plugins for esound and for libmikmod or
whatever

function call overhead (if not optimized out by compiler). But it does
not matter atm too :)
