Remarks
The CFileException class includes public data members that hold the portable cause code and the operating-system-specific error number. The class also provides static member functions for throwing file exceptions and for returning cause codes for both operating-system errors and C run-time errors.
CFileException objects are constructed and thrown in CFile member functions and in member functions of derived classes. You can access these objects within the scope of a CATCH expression. For portability, use only the cause code to get the reason for an exception. For more information about exceptions, see the article Exception Handling (MFC).
