al_set_phy..._interface(3)

✨ al_set_physfs_file_interface(3) — Allegro 5 API ✨

Okay bestie, so this one's from the Allegro reference manual and it's literally the glow-up for your file I/O when you wanna vibe with PhysicsFS instead of the default Allegro filesystem. No cap, it's a whole thing. Let's get into it 💅

🎀 NAME 🎀

al_set_physfs_file_interface — Allegro 5 API 🦋

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_physfs.h>

void al_set_physfs_file_interface(void)

---

💖 DESCRIPTION 💖

So this function is iconic — it sets both the ALLEGRO_FILE_INTERFACE(3) and the ALLEGRO_FS_INTERFACE(3) for the calling thread. Like, both at once. Main character energy fr fr 👑

After you call this, any subsequent calls to al_fopen(3) on the calling thread get handled by PHYSFS_open(). And operations on the files that al_fopen(3) returns will then be performed through PhysicsFS. Slay 💅

Calls to the Allegro filesystem functions — think al_read_directory(3) or al_create_fs_entry(3) — on the calling thread get diverted to PhysicsFS too. It's giving full takeover, periodt.

Now, if you wanna remember and restore another file I/O backend, you can use al_store_state(3) / al_restore_state(3). Cute, right? 🎀

Note: due to an oversight, this function differs from al_set_new_file_interface(3) and al_set_standard_file_interface(3) — those two only alter the current ALLEGRO_FILE_INTERFACE(3). So like, lowkey this one does more. Just a heads up bestie 🙈

Note: PhysFS does not support the text-mode reading and writing, which means that Windows-style newlines will not be preserved. So don't come for me when your \r\n goes missing, okay? It's literally not supported 😭

That's the whole vibe, bestie. This page came straight from the Allegro reference manual — no date drama, just the classic. Now go set that file interface and live your best life ✨💖🎀🦋🌸💅
