Is there any way to open a file in Windows using ONLY the FRN?

Is there any way to open a file in Windows using ONLY the FRN (File Reference Number)?

This is for a file system that does NOT support change journal, but it does support FRN. I need to be able to open the file only using the FRN, and I'm looking for a Windows API that would allow me to do that.

Perhaps this helps?

IoCreateFile, with flag FILE_OPEN_BY_FILE_ID
