SDL_TRY_ACQUIRE(3)

💅 NAME 💅

SDL_TRY_ACQUIRE — bestie it's literally just a wrapper around the Clang thread safety analysis annotations. That's the whole vibe. It's giving "middle manager for your compiler's anxiety". 🎀

---

✨ SYNOPSIS ✨

okay so first you gotta pull in the header, no cap:

#include <SDL3/SDL_mutex.h>

and then here's the macro itself, copied exactly, do NOT freestyle this:

#define SDL_TRY_ACQUIRE(x, y) \
  SDL_THREAD_ANNOTATION_ATTRIBUTE__(try_acquire_capability(x, y))

yes the backslash is real, yes it's doing the line-continuation thing, she's iconic like that 💜

📖 DESCRIPTION 📖

There is genuinely nothing more to say here, the whole description is a link and I'm not about to invent lore that isn't there:

Please see https://clang.llvm.org/docs/ThreadSafetyAnalysis.html#mutex-h

go read the clang docs bestie, they're the main character of this story, I'm just the messenger 🦋

🌸 AVAILABILITY 🌸

This macro has been available since SDL 3.2.0. So if you're on anything older than that… girl. 😭 Update. Please. For me. 🫶

ngl this one is short but she's important — if your compiler doesn't do thread safety analysis this macro basically vibes out and does nothing visible, and that's by design, so don't come for her. ✨

okay that's the whole page, short and sweet, a little snack of a manpage 🍓

this was brought to you by Simple Directmedia Layer, version SDL 3.4.18, and this page is SDL_TRY_ACQUIRE(3). mwah, take care of your mutexes, bye bestie 💖👑🌈
