SDL_THREAD_A...N_ATTRIBUTE__(3)

✨ SDL_THREAD_ANNOTATION_ATTRIBUTE__ ✨

okay bestie, so this one lives in the SDL3 FUNCTIONS corner of the SDL 3 universe, and it's literally just a tiny macro that lets clang do thread-safety analysis on your code. that's it. that's the whole girl. 🎀

---

🌸 NAME 🌸

SDL_THREAD_ANNOTATION_ATTRIBUTE__</p> — turns on thread safety attributes, and like… only with clang, no cap.

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_mutex.h>

#define SDL_THREAD_ANNOTATION_ATTRIBUTE__(x)   __attribute__((x))

---

💖 DESCRIPTION 💖

so the tea is: these attributes can be safely erased when you're compiling with other compilers. meaning if clang isn't the one holding the aux cord, this macro just vibes out and disappears. no drama, no broken builds. 🫶

if you do wanna enable the analysis (main character move honestly), you gotta set these environment variables before running cmake:

export CC=clang
export CFLAGS="-DSDL_THREAD_SAFETY_ANALYSIS -Wthread-safety"

⚠️ key word being before. set them after cmake has already run and it's giving… too late bestie 😭 the analysis simply will not show up.

that's the whole page. short, sweet, iconic. 💅

Simple Directmedia Layer wrote this one, it's from the SDL 3.4.18 era, and it's filed under SDL_THREAD_ANNOTATION_ATTRIBUTE__(3). mwah, bye, go compile something cute 💜🌈✨
