Windows System Error Code
From Just Solve the File Format Problem
Windows System Error Codes are numeric error codes used by many Microsoft Windows API functions. Earlier operating systems, notably MS-DOS, use a subset of these codes.
Code 0 means "success", and positive integers represent errors.
See also HRESULT.
