Sure.
If rename fails, then either the file doesn't exist (you can check
that) or it is locked.
If rename doesn't fail, then you can open it with it's new name.

This has the advantage that the writter can start writing right away.

You can also use CreateFile() with the FILE_FLAG_DELETE_ON_CLOSE
option to read and delete the file.
