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.
