SDL_LoadFile_IO
Available since SDL 3.2.0.
Load all the data from a file path, asynchronously.
This function returns as quickly as possible; it does not wait for the read to complete. On a successful return, this work will continue in the background. If the work begins, even failure is asynchronous: a failing return value from this function only means the work couldn't start at all.
The data is allocated with a zero byte at the end (null terminated) for convenience. This extra byte is not included in SDL_AsyncIOOutcome's bytes_transferred value.
This function will allocate the buffer to contain the file. It must be deallocated by calling SDL_free on SDL_AsyncIOOutcome's buffer field after completion.
An SDL_AsyncIOQueue must be specified. The newly-created task will be added to it when it completes its work.
