TS_OPEN_RESTRICTED(3)

💖 ts_open_restricted — the manual page, but make it make sense 💖

okay bestie, welcome to tslib's ts_open_restricted(3) page, except now it's fun and also you'll actually remember it. sit down, hydrate, let's go 🫶

✨ NAME ✨

ts_open_restricted — the way you plug in your own little custom function for opening the touchscreen's input device file. yes, YOUR function. you're the main character now 👑

🌸 SYNOPSIS 🌸

#include <tslib.h>

int (*ts_open_restricted)(const char *path, int flags, void *user_data);

that's it, that's the whole vibe. a function pointer, living its best life ✨

🦋 DESCRIPTION 🦋

so ts_open_restricted() is the icon we call when libts should not be run as root. like, imagine not wanting your whole touchscreen stack to have god-mode privileges. valid. iconic. security-conscious 💅

if you implement a function like this yourself and assign it to the ts_open_restricted pointer, then ts_open() will call your function instead of hitting the open() system call directly. the way that works is literally chef's kiss 🎀

your function should open the input device at path with flags, while user_data is currently unused. that's it. do your thing, bestie 💖

heads up: user_data is currently unused — don't go building your whole personality around it, fr fr 🙈

⭐ RETURN VALUE ⭐

the touchscreen input device's file descriptor. give it back, it's what the people want 🫶
