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 re- turns 0xFFFF it is an external device like an MPU-401 where there is no way to determine how many voices are available. SEE ALSO install_sound(3), reserve_voices(3) Allegro version 4.4.3 detect_midi_driver(3)
