Detailed Description

A queue of completed asynchronous I/O tasks.

When starting an asynchronous operation, you specify a queue for the new task. A queue can be asked later if any tasks in it have completed, allowing an app to manage multiple pending tasks in one place, in whatever order they complete.

Since

This struct is available since SDL 3.2.0.

AsyncIOQueue()

SDL::AsyncIOQueue::AsyncIOQueue ( AsyncIOQueueRaw resource )

inlineexplicitconstexprnoexcept

Constructs from raw AsyncIOQueue.

Parameters

resource

a AsyncIOQueueRaw to be wrapped.

This assumes the ownership, call release() if you need to take back.
