set_hardware_volume(3)          Allegro manual          set_hardware_volume(3)



NAME
       set_hardware_volume - Alters the hardware sound output volume. Allegro
       game programming library.

SYNOPSIS
       #include <allegro.h>


       void set_hardware_volume(int digi_volume, int midi_volume);

DESCRIPTION
       Alters the hardware sound output volume. Specify volumes for both
       digital samples and MIDI playback, as integers from 0 to 255, or pass a
       negative value to leave one of the settings unchanged. Values bigger
       than 255 will be reduced to 255. This routine will use the hardware
       mixer to control the volume if it exists (i.e. the volume of all the
       applications on your machine will be affected), otherwise do nothing.
