Question for the implementation of reading a file.

[lch32111]

Thank you for sharing your awesome work of reading obj data quickly!
I am referring to your implementation for my game engine.

While reading your implementation, I was curious about why you replaced the aio with readahead+pread64 on the linux platform.
Could you share anything about this? I have little experience on this kind of topic.

Thanks.

I think that you are using a wrong variable for GetOverlappedResult here:

rapidobj/include/rapidobj/rapidobj.hpp

Line 5067 in 744374a

bool success = GetOverlappedResult(m_handle, &m_overlapped, &bytes_read, TRUE);

m_handle is the Event object created like this:

rapidobj/include/rapidobj/rapidobj.hpp

Line 5014 in 744374a

m_handle = CreateEventA(nullptr, FALSE, FALSE, nullptr);

According to MSDN, the first parameter of GetOverlappedResult should be a handle to the file, named pipe, or communication device. You can also find an example from here.
