💖 register_datafile_object (3alleg4) 💖

okay bestie, welcome to the Allegro manual — yes the Allegro manual, the one that lives at section 3alleg4 of your man pages, and today we're doing register_datafile_object. pull up a chair, grab a strawberry 🍓, this one's short and sweet.

✨ NAME ✨

register_datafile_object — it registers your load/destroy functions for custom object types, and it's part of the Allegro game programming library. that's literally the whole job description, she's focused 💅

🎀 SYNOPSIS 🎀

#include <allegro.h>

void register_datafile_object(int id, void *(*load)(PACKFILE *f, long size), void (*destroy)(void *data));

like… look at that signature. three arguments. two of them are function pointers. she's giving callback energy and honestly? iconic 👑

🦋 DESCRIPTION 🦋

so here's the tea, bestie 🫖 — you use register_datafile_object to add your own custom object types to the datafile system. you hand it an id, and you hand it the two functions that do the actual work: one to load objects of that type, and one to destroy them. that's it. that's the vibe.

think of it like introducing your new friend to the group chat: you say "hey everyone, this is the id," and then you give the chat two contacts — the load one for when somebody needs to bring them into the conversation, and the destroy one for when it's time to go home 😭 no cap, that's the whole function.

so: custom object type in, load function and destroy function specified, and Allegro knows what to do with objects of that type from then on. slay ✨

🌸 SEE ALSO 🌸

go read those next, they're the rest of the little datafile family and they all eat 💖

fr fr, if you're registering custom types, make sure your load and destroy functions actually match up with each other — one brings the object into being, the other cleans it up. balance. harmony. main character energy 🌈

and that's the page!! this one came to you from Allegro, version 4.4.3 — huge shoutout to the Allegro manual for having her, we're obsessed 🫶 bye bestie, go write some datafile code 💜🧚‍♀️
