✨ find_datafile_object(3) ✨

okay bestie, welcome to the Allegro manual 🎀 this one is find_datafile_object and it's genuinely one of those little functions that saves your whole entire life, no cap 💖

🌸 NAME 🌸

find_datafile_object — searches a datafile for an object with a name. Part of the Allegro game programming library 🦋

💅 SYNOPSIS 💅

#include <allegro.h>

DATAFILE *find_datafile_object(const DATAFILE *dat, const char
*objectname);

🫶 DESCRIPTION 🫶

so you've already got a datafile loaded, right? and now you're like "girl where is my object" 😭 — this function goes digging through that loaded datafile and finds the object with the name you asked for. obsessed.

and here's the cute part: in the name, you can use /' and #' separators for nested datafile paths ✨ so you can reach into datafiles inside datafiles, iykyk.

like, for example 💫:

char level_name[10];
DATAFILE *dat, *level;
...
uszprintf(level_name, sizeof(buffer),
          "LEVEL_%02d", level_number);
level = find_datafile_object(dat, level_name);
if (!level)
   abort_on_error("That level doesn't exist!");

see how it just... finds the level? main character energy fr fr 👑

⭐ RETURN VALUE ⭐

it hands you back a pointer to a single DATAFILE element whose dat member points to the object 💖 — or NULL if the object could not be found 🥲 (and you should always check for that NULL, bestie, do not skip the vibe check).
