For debugging it is helpful to know the address of the file handle created by the Open() method of the EFI file protocol. So let's write it with EFI_PRINT().
Just a question. How will you use the address for debugging?
The handle address is shown by EFI_ENTRY in SetInfo(), GetInfo(), Read(), ...
This helped me to understand for which file GetInfo() was failing in the EFI Shell.
