load_joystick_data(3alleg4)

💖 NAME 💖

load_joystick_data — loads joystick calibration data, bestie. It's the Allegro game programming library, and this little function is literally the glow-up your joystick deserves. 🎮✨

🌸 SYNOPSIS 🌸

#include <allegro.h>

int load_joystick_data(const char *filename);

🦋 DESCRIPTION 🦋

Okay so picture this: somebody already did the work. save_joystick_data() wrote all that calibration data down, or the setup utility did, and now you just want it back. That's this function. It restores calibration data previously stored by save_joystick_data() or the setup utility. 🫶

And here's the part that's giving main character energy: this sets up all aspects of the joystick code. All of them. Every single one. So you don't even need to call install_joystick() if you're using this function — it's already handled, no extra steps, periodt. 👑

Wanna read from the currently selected configuration file instead of a real file? Pass a NULL filename, babe. That's it. Pass a NULL filename to read the data from the currently selected configuration file. 🎀

⭐ RETURN VALUE ⭐

Returns zero on success. Slay. 🎉

But if it fails? Oop. 😭 The joystick state is undefined — like, genuinely unknown, nobody knows what's in there — and you must reinitialise it from scratch. No shortcuts, no vibes-based recovery. Start over, babe. 💀

fr fr do NOT trust the joystick state after a failure. Undefined means undefined. Reinitialise from scratch and move on. 🙈
