SDL_SignalAsyncIOQueue3
Wake up any threads that are blocking in sdl_waitasyncioresult ().
Usage
#include "SDL3/SDL.h"
void SDL_SignalAsyncIOQueue(SDL_AsyncIOQueue *queue);
Header file
Defined in SDL3/SDL_asyncio.h
Overview
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.
