DM9000冷启动设置

DM9000冷启动，不需要重新编译内核，以下C#程序在WINCE6.0系统下运行：

 

        const Byte IO_CTL_DM9000_RESET = 0x14;
        private const int IOCTL_NDIS_REBIND_ADAPTER = 1507374;
        private const int IOCTL_NDIS_GET_ADAPTER_NAMES = 1507386;
        private const string EtherCardFileName = "NDS0:";
        private const int FILE_ATTRIBUTE_NORMAL = 0x80;
        private static string EtherCardName = "DM9CE1\0";

 

        [DllImport("Coredll.dll", EntryPoint = "CreateFile")]
        private static extern int CreateFile(
                string lpFileName,
                int dwDesiredAccess,
                int dwShareMode,
                int lpSecurityAttributes,
                int dwCreationDisposition,
                int dwFlagsAndAttributes,
                int hTemplateFile
            );

        [DllImport("Coredll.dll", EntryPoint = "DeviceIoControl")]
        private static extern int DeviceIoControl(
                int hDevice,
                int dwIoControlCode,
                string lpInBuffer,
                int nInBufferSize,
                string lpOutBuffer,
                int nOutBufferSize,
                int lpBytesReturned,
                int lpOverlapped
            );

        [DllImport("Coredll.dll", EntryPoint = "CloseHandle")]
        private static extern int CloseHandle(int hObject);

       
        public static bool resetDM9000()
        {
            int hNdis = CreateFile(EtherCardFileName, 0, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,INVALID_HANDLE_VALUE);
            if (hNdis == INVALID_HANDLE_VALUE)
            {
                return false;
            }

            // Send the device command.
            if (DeviceIoControl(hNdis, IOCTL_NDIS_REBIND_ADAPTER, EtherCardName, EtherCardName.Length * 2 + 2, null, 0, 0, 0) == 0)
            {
                return false;
            }

            CloseHandle(hNdis);
            return true;
        }
