Check if file can be renamed (moved) without copying

QFile::rename description says:

If the rename operation fails, Qt will attempt to copy this file's contents to newName, and then remove this file, keeping only newName.

That is undesirable. I need to call QFile::rename only if the file can be renamed without copying (e. g. remains on the same disk drive on Windows). Is there a function in Qt that can perform this check (without me having to code it manually for every platform)?

I've ended up getting and checking the drive number on Windows (PathGetDriveNumber) and drive ID on Unix (stat function and st_dev field of the stat structure). Seems to work as expected so far.
