SDL_SignalAsyncIOQueue - Man Page
Wake up any threads that are blocking in SDL_WaitAsyncIOResult ().
Header File
Defined in SDL3/SDL_asyncio.h
Synopsis
#include "SDL3/SDL.h" void SDL_SignalAsyncIOQueue(SDL_AsyncIOQueue *queue);
Description
This will unblock any threads that are sleeping in a call to
SDL_WaitAsyncIOResult
for the specified queue, and cause them to return from that function.
This can be useful when destroying a queue to make sure nothing is touching it indefinitely. In this case, once this call completes, the caller should take measures to make sure any previously-blocked threads have returned from their wait and will not touch the queue again (perhaps by setting a flag to tell the threads to terminate and then using
SDL_WaitThread () to make sure they've done so).
Function Parameters
- queue
the async I/O task queue to signal.
Thread Safety
It is safe to call this function from any thread.
Availability
This function is available since SDL 3.2.0.
