al_identify_bitmap_f(3)

okay so this is al_identify_bitmap_f(3) from the Library Functions Manual, and it’s literally the Allegro 5 API page for guessing what kind of bitmap file you just opened. bestie, it’s giving “detective but make it file extensions.” 💅

🌸 NAME 🌸

al_identify_bitmap_f — Allegro 5 API. that’s the whole NAME entry, periodt.

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

char const *al_identify_bitmap_f(ALLEGRO_FILE *fp)

🦋 DESCRIPTION 🦋

So this function tries to guess the bitmap file type of the open ALLEGRO_FILE by reading the first few bytes. lowkey iconic behavior. 🔥

By default, Allegro cannot recognize any file types — yes, literally none, no cap. But calling al_init_image_addon(3) will add detection of (some of) the types it can read. You can also use al_register_bitmap_identifier(3) to add identification for custom file types. slay, customization. ✨

It returns a pointer to a static string with a file extension for the type, including the leading dot. For example .png or .jpg. Returns NULL if the bitmap type cannot be determined. that’s the vibe check, fr fr. 😭

sign-off: this came from the Allegro reference manual, footer tag al_identify_bitmap_f(3), and the footer doesn’t show a date — so we’re not making one up, bestie. 🫶🎀
