使用win32 api读文件

    BOOL    bResult;
    HANDLE  hFile;
    //
    hFile = ::CreateFile(TEXT("e:/test.txt"),
        GENERIC_READ,
        0,
        NULL,
        OPEN_EXISTING,
        FILE_ATTRIBUTE_NORMAL, 
        NULL);
    //
    if (hFile == INVALID_HANDLE_VALUE)
    {
        return;
    }

    //
    char  readBuffer[1024];
    ZeroMemory(readBuffer, sizeof(readBuffer));
    DWORD dwBytesRead =  0;
    DWORD dwError = 0;

    bResult = ::ReadFile(hFile, readBuffer, 4, &dwBytesRead, NULL);
    if (!bResult)
    {
    	return;
    }
