💅 al_set_d3d...e_callback(3)

okay so bestie, this is a page from the Allegro reference manual, and honestly? it's a tiny one but it's important if you're doing Direct3D stuff. sit with me for a sec 🫶

✨ NAME ✨

al_set_d3d_device_restore_callback — it's part of the Allegro 5 API, and it's the little function that hooks you up with a callback for when your D3D device comes back to life 💖

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_direct3d.h>

void al_set_d3d_device_restore_callback(
   void (*callback)(ALLEGRO_DISPLAY *display))

like, that's the whole signature. slay. no extra params, no weird surprises, just a function pointer and vibes ✨

🎀 DESCRIPTION 🎀

so here's the tea ☕ — the callback you pass in gets called whenever a D3D device that has been reset is restored. that's the moment. that's its whole moment. 🔥

and when that happens, inside your callback you should restore any d3d resources you've created yourself. yes, you. the ones you made. the device came back but your stuff might not have, so this is your little window to fix it up. the callback receives the affected display as a parameter, so you know exactly which display is going through it 👑

also, important: pass NULL to disable the callback. no callback, no problem, no call. lowkey the simplest off switch ever 💀

ngl this is one of those "if you know you know" functions — but if you're managing your own d3d resources, you do know, and you need it 💅
