Proper waiting for file to download

[Kubas556]

Hi, I would like to ask how to properly handle read operation, when the file is still downloading. I searched the microsoft documentation of NtReadFile function and found nothing about this case. Closest is to return STATUS_PENDING status, but after that the read function will never be called again.

Thanks.

Hi @Kubas556 ,
STATUS_PENDING shouldn't be returned by userland filesystem. Dokany actually already respond to IRP with STATUS_PENDING to give you time to process the read. What you need to do is to wait for the download to happen, maybe call TryResetTimeout if it takes too long and return the result when you can.

I will try that
