To check if a call that returns an HRESULT succeeded, make sure the S field is 0 (i.e. There are some generic Win32 error codes defined: ERROR_FILE_NOT_FOUND: "The system cannot find the file specified." that of course i could use for my own purpose when a file is not S_FALSE=0x01. As others have said, there is no way to get those capitalized, underscored names, short of looking them up in winerror.h, which I have seen reproduced online in various places where https://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx
