detect_midi_driver(3)		 Allegro manual 	   detect_midi_driver(3)

NAME
     detect_midi_driver  -  Detects  whether  the specified MIDI sound device is
     available. Allegro game programming library.

SYNOPSIS
     #include <allegro.h>

     int detect_midi_driver(int driver_id);

DESCRIPTION
     Detects whether the specified MIDI sound device is available. This function
     must be called _before_ install_sound().

RETURN VALUE
     Returns the maximum number of voices that the driver can provide,	or  zero
     if the hardware is not present.

     There  are two special-case return values that you should watch out for: if
     this function returns -1 it is a note-stealing  driver  (eg.  DIGMID)  that
     shares  voices  with  the	current  digital sound driver, and if it returns
     0xFFFF it is an external device like an MPU-401 where there is  no  way  to
     determine how many voices are available.
