WinAPI::getFullPathName

[Sergikrus]

Написал следущую обёртку для функции getFullPathName:

client static Filename getFullPathName(Filename _filename)
{
    DLL             _winApiDLL          = new DLL(#KernelDLL);
    DLLFunction     _getFullPathName    = new DLLFunction(_winApiDLL, 'GetFullPathNameW');
    Binary          bufer               = new Binary(#MAX_PATH);
    ;
    _getFullPathName.returns(ExtTypes::DWord);
    _getFullPathName.arg(ExtTypes::WString,
                         ExtTypes::Pointer,
                         ExtTypes::WString,
                         ExtTypes::WString);
    if(_getFullPathName.call(_filename, #MAX_PATH*2, bufer, null))
    {
           _getFullPathName.call(_filename, #MAX_PATH*2, bufer, null);
           return bufer.wString(0);
    }
    return '';
}

вызываю в Job - е:

static void WinAPIgetFullPathName(Args _args)
{
    Filename filename;
    ;

    filename = winAPI::getFullPathName("myfile.txt");
    info(strfmt("%1", filename));
}

Ничего не возвращает, подскажите если можете в чём ошибка
