How to get name associated with open HANDLE

Question

What\'s the easiest way to get the filename associated with an open HANDLE in Win32?

Answer 1

For Windows Vista and later I prefer to use GetFinalPathNameByHandle()

char buf[MAX_PATH];
GetFinalPathNameByHandleA(fileHandle, buf, sizeof(buf), VOLUME_NAME_DOS)

For Windows XP I prefer the solution by Mehrdad.

So I load GetFinalPathNameByHandle() dynamically via GetProcAddress() and if this fails (because it's Windows XP) I go for Mehrdad's solution with NtQueryObject()
