detect_midi_driver(3)

💖 detect_midi_driver(3) — Allegro manual 💖

okay bestie, we're diving into the Allegro game programming library manual, and this one is literally about checking if your MIDI sound device is even there. no cap. let's get into it. ✨

🌸 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 💖

so detect_midi_driver() checks whether the MIDI sound device you specified is available. it's giving "hey bestie, you up?" energy. 🦋

🚨 the one rule 🚨: this function must be called _before_ install_sound(). like, before before. not after. the way that order matters is real. 💀

✨ RETURN VALUE ✨

it returns the maximum number of voices that the driver can provide, or zero if the hardware is not present. so if you get 0, the hardware said "not me". 🙈

there are two special-case return values that you should watch out for:

• if this function returns -1, it's a note-stealing driver (eg. DIGMID) that shares voices with the current digital sound driver. 👑
• if it returns 0xFFFF, it's 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)

and that's the whole vibe. Allegro manual, version 4.4.3, signing off. periodt 💅✨
