💅 al_acknowledge_resize(3) — Library Functions Manual ✨

okay so real quick, bestie, the manual we're in is the Allegro reference manual and the page is al_acknowledge_resize(3) — it's a Library Functions Manual situation. Allegro 5 API, if you're fancy. let's get into it 🫶

---

🌸 NAME 🌸

al_acknowledge_resize — literally the Allegro 5 API function that tells the graphics driver "yeah okay you can resize now" 💖

---

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

bool al_acknowledge_resize(ALLEGRO_DISPLAY *display)

that's it, that's the whole signature, no cap 🌈

---

🎀 DESCRIPTION 🎀

so picture this: you've got a resizable display, and the user goes and triggers a resize — which means you, the programmer, receive a [resize event] ALLEGRO_EVENT_DISPLAY_RESIZE(3). if you actually want the display to resize (and like, valid choice if you do 💅), you must call this function so the graphics driver knows it's free to go ahead and resize the display now. it returns true on success. slay. ✅

on top of that, this bad boy adjusts the clipping rectangle to the full size of the backbuffer — so nothing's getting weirdly clipped, iconic. 🦋

it also resets the backbuffer's projection transform back to the default orthographic transform. (peep al_use_projection_transform(3) if you wanna know more about that, iykyk.)

⚠️ okay important heads-up, bestie: a resize event can be outdated by the time you get around to acknowledging it 😭 there could be further resize events generated in the meantime. so like, don't be shocked. it's giving "the timeline moved on without you." fr fr 💀
