SDL_SetAtomicInt(3)

πŸ’… NAME πŸ’…

okay bestie, gather round β€” SDL_SetAtomicInt is the one that sets an atomic variable to a value. that's it. that's the whole job. she's simple, she's powerful, she's iconic. πŸŽ€

int SDL_SetAtomicInt(SDL_AtomicInt *a, int v);

like. look at her. two args, one return, zero drama. πŸ¦‹


🌸 DESCRIPTION 🌸

so basically this function also acts as a full memory barrier. that part is lowkey the whole point, bestie β€” it's not just "assign a number," it's "assign a number and make sure everything before and after plays nice in the right order." main character behavior, no cap. πŸ’…
