There are doubts:

1) we always use system function (GetFinalPathNameByHandleA or
GetFileInformationByHandle); sometimes we use these two calls
GetFinalPathNameByHandleA + GetFileInformationByHandle
together (in freopen() case);

2) function GetFinalPathNameByHandleA is slower than
GetFileInformationByHandle (2-4 times).
Might be exist a cheaper way than GetFinalPathNameByHandleA?

I don't understand why this way better than using one call
GetFileInformationByHandle...
