DlnOpenDevice() Function

The DlnOpenDevice() function opens the specified device. This function uses an index number of the device. This number is randomly system-assigned to each connected device. It cannot be used to identify the device. If you need to open a specific device, use the DlnOpenDeviceBySn() or DlnOpenDeviceById() functions.

DLN_RESULT DlnOpenDevice(
   uint32_t deviceNumber,
   HDLN* deviceHandle
);
Parameters

A number of the device.

deviceHandle

A pointer to the HDLN type variable that receives the device handle.

Return Value

DLN_RES_NOT_CONNECTED (0xA1)

The library is not connected to any server.

DLN_RES_MEMORY_ERROR (0x86)

Not enough memory to process this command.

DLN_RES_HARDWARE_NOT_FOUND (0x81)
