Exception in Windows constructing file_handle

[tastewar]

We occasionally encounter an exception on Windows when calling the file_handle constructor as follows:

llfio::file_handle newfile = llfio::file({}, rafPath, llfio::file_handle::mode::write, llfio::handle::creation::only_if_not_exist).value();

This ends up calling your CreateFileW_ function internally, which then executes:

if(RtlDosPathNameToNtPathName_U(lpFileName, &NtPath, nullptr, nullptr) == 0u)

And we get an Access violation executing location 0, as if the return address on the stack has been corrupted.

This happens infrequently, and on the most recent instance, the file indeed did not exist at the time of the call, and there was only one thread of execution at that point in time.

Will do some testing. Thanks.

As far as we can tell, this has solved the problem. Thank you.
