I tested 2 cases:

1) "stdout" is not redirected.
In this case GetFinalPathNameByHandleA() returns error and 
GetFileInformationByHandle() returns error.
Simple test in attachment.

Result:
GetFileInformationByHandle: 7, GetFinalPathNameByHandleA: 16

2) "stdout" redirected (need to uncomment 2 lines in test).
Both function works without error.
---
Result (see file "1.txt"):
GetFileInformationByHandle: 34, GetFinalPathNameByHandleA: 120

The difference is not very big, but it is.

With best regards,
Dmitry.
