SDL_TryLockSpinlock(3)

💖 SDL_TryLockSpinlock 💖

okay bestie, gather round, we're in the SDL3 FUNCTIONS section of the manual and today's main character is SDL_TryLockSpinlock(3). she's a lil function that tries to lock a spin lock by setting it to a non-zero value. no drama, no waiting around, she just goes for it. 💅

---

✨ SYNOPSIS ✨

#include <SDL3/SDL_atomic.h>

bool SDL_TryLockSpinlock(SDL_SpinLock *lock);

like yes, that's the whole vibe. one include, one function, one pointer. iconic. 🎀

🌸 DESCRIPTION 🌸

so real talk, bestie: spinlocks are dangerous if you don't know what you're doing. that's not me being dramatic, that's the manpage being dramatic and I'm just relaying it. 🫶

⚠️ Please be careful using any sort of spinlock! ⚠️

she said what she said. if you're not 100% sure about your locking situation, maybe sit this one out and let the pros handle it. iykyk. 💀
