SDL_UpdateSensors(3)

✨ SDL_UpdateSensors(3) ✨

okay bestie, welcome to the SDL_UpdateSensors page, part of the SDL3 functions crew 🎀 like, it's a whole manual page, and we're gonna read it together, no cap.

🌸 NAME 🌸

SDL_UpdateSensors — update the current state of the open sensors 💅

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_sensor.h>

void SDL_UpdateSensors(void);

literally that's the whole signature, she's simple, she's iconic, she takes no arguments and gives back void. periodt. ✨

💖 DESCRIPTION 💖

so here's the tea ☕ — this function refreshes the current state of the open sensors. that's it, that's the job.

the event loop calls this automatically for you if sensor events are enabled. so like, if you've got sensor events turned on, she's already showing up to the party without you having to text her. 🙈

but important: this needs to be called from the same thread that initialized the sensor subsystem. not a different thread. not your friend's thread. the one that initialized it. the way that threading rules apply here is giving main character energy and honestly? respect it. 🫶

ngl if you call this from the wrong thread you're kinda asking for chaos, so just… don't. 💀

🌈 AVAILABILITY 🌈

this function is available since SDL 3.2.0. so if you're on anything older, she's not there yet, sorry bestie. 😭

and that's the whole page, you ate that 🍓 go forth and update your sensors responsibly, iykyk.
