TS_CLOSE_RESTRICTED(3)

✨ TS_CLOSE_RESTRICTED(3) ✨

okay so bestie, welcome to the tslib manual, section 3, and today's main character is ts_close_restricted 💅

🎀 NAME 🎀

ts_close_restricted — the way you drop in your own custom function for closing the touchscreen's input device file 🫶

🌸 SYNOPSIS 🌸

#include <tslib.h>

void (*ts_close_restricted)(int fd, void *user_data);

💖 DESCRIPTION 💖

so here's the vibe: ts_close_restricted() is useful if libts should not be run as root. like, imagine not wanting to hand root privileges to your touchscreen library — valid, honestly, iconic even 👑

if you (the user) implement a function like that and assign it to the ts_close_restricted pointer, then ts_close() will call your function instead of hitting the close() system call directly. no cap. it's literally a little swap-in-and-slay situation 🔥

and what should that function do? it should obviously close the device with file descriptor fd 🌈 meanwhile user_data is currently unused — so yeah, it's just kinda sitting there looking cute, not doing anything yet 🙈

not me making you read a whole paragraph for "close the fd but make it custom" 💀 but fr fr, every word of it matters.
