load_datafile_object(3alleg4)

✨ load_datafile_object ✨

okay bestie, welcome to the Allegro manual 💖 — this one's from the Allegro game programming library, and it's about grabbing one single object out of a datafile instead of dragging the whole thing into memory. iconic behavior, honestly. 🎀

🌸 NAME 🌸

load_datafile_object — loads a specific object from a datafile. Allegro game programming library. no cap, that's literally it. 🦋

💅 SYNOPSIS 💅

#include <allegro.h>

DATAFILE *load_datafile_object(const char *filename, const char
*objectname);

👑 DESCRIPTION 👑

So like, this loads a specific object from a datafile. Just the one. Your fave. Your little guy. 🫶

But bestie, hear me out, there are two big catches:

• It won't work if you strip the object names from the file. The names gotta stay, periodt. 💀
• It will be very slow if you saved the file with global compression. like, painfully slow. not the vibe. 😭

Example, because we love a demonstration:

/* Load only the music from the datafile. */
music_object = load_datafile_object("datafile.dat",
                                    "MUSIC");
/* Play it and wait a moment for it. */
play_midi(music_object->dat);
...
/* Destroy unneeded music. */
unload_datafile_object(music_object);

⭐ RETURN VALUE ⭐

It returns a pointer to a single DATAFILE element whose dat member points to the object. 💫

Or NULL if there was an error, or if there was no object with the requested name. so like, if you typo'd the name, that's on you, and you get NULL. 🙈

⚠️ Remember to free this DATAFILE later to avoid memory leaks, but use the correct unloading function! don't just freestyle it, bestie, that's how leaks happen. 💀
