Large_Integer SetFilePointerEx Error 183

[Luckie]

Äh:

Code:

Return value

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Das:

Delphi-Quellcode:

if SetFilePointerEx(hFile, li, nil, FILE_BEGIN) <> 0 then
    Result := GetLastError();

ist also falsch. Du musst auf Null testen.
