SDL_GetCurrentThreadID(3)

✨ SDL_GetCurrentThreadID ✨

okay bestie, welcome to the manual page for SDL_GetCurrentThreadID(3) 💖 this one lives in the SDL3 FUNCTIONS fam and it's literally the easiest lil glow-up in the whole thread API. let's get into it 🫶

---

🌸 NAME 🌸

SDL_GetCurrentThreadID — bestie, it hands you the thread identifier for the thread you're standing in right now. that's it. that's the whole job 💅

---

🎀 SYNOPSIS 🎀

#include <SDL3/SDL_thread.h>

SDL_ThreadID SDL_GetCurrentThreadID(void);

no arguments, no drama, just vibes ✨

---

🦋 DESCRIPTION 🦋

so like. this thread identifier is the one as reported by the underlying operating system — it's not some SDL-invented number, it's the real OS one, no cap.

⚠️ important tea: if SDL is running on a platform that does not support threads, the return value will always be zero. zero. every time. so don't go treating 0 like a real thread ID on those platforms, bestie 😭

and the slay part? this function also returns a valid thread ID when called from the main thread. yes, even the main character thread gets a proper ID. main character energy fr fr 👑

---

💜 RETURN VALUE 💜

it returns the ID of the current thread. that's the whole gift. the current thread's ID. iconic. 💅

---

🔥 THREAD SAFETY 🔥

it is safe to call this function from any thread. any of them. all of them. go wild, no notes 🫶

---

⭐ AVAILABILITY ⭐

this function is available since SDL 3.2.0 🎀 so if you're on anything older, she's not there yet, sorry babe 🙈
