Destroy a previously-created async I/O task queue.
Defined in <SDL3/SDL_asyncio.h>
void SDL_DestroyAsyncIOQueue(SDL_AsyncIOQueue *queue);| SDL_AsyncIOQueue * | queue | the task queue to destroy. |
If there are still tasks pending for this queue, this call will block until those tasks are finished. All those tasks will be deallocated. Their results will be lost to the app.
Any pending reads from SDL_LoadFileAsync() that are still in this queue will have their buffers deallocated by this function, to prevent a memory leak.
Once this function is called, the queue is no longer valid and should not be used, including by other threads that might access it while destruction is blocking on pending tasks.
Do not destroy a queue that still has threads waiting on it through SDL_WaitAsyncIOResult(). You can call SDL_SignalAsyncIOQueue() first to unblock those threads, and take measures (such as SDL_WaitThread()) to make sure they have finished their wait and won't wait on the queue again.
It is safe to call this function from any thread, so long as no other thread is waiting on the queue with SDL_WaitAsyncIOResult.
This function is available since SDL 3.2.0.
