Ubuntu - Alsa master volume

[QIZI94]

Hello,
I have been searching for some way to get system audio volume through c++ and I haven't found anything.
Do somebody know some easy way to get system volume ? even throught some file ?

Here's the ALSA library API: http://www.alsa-project.org/alsa-doc/alsa-lib/index.html

Also found this: http://stackoverflow.com/questions/6787318/set-alsa-master-volume-from-c-code

To get the system audio volume use snd_mixer_selem_get_playback_volume() instead.

Thanks, snd_mixer_selem_get_playback_volume() work perfectly for me.
