*
* Sends data to the device.
*
* Before device data can be sent to a device,
* the device must be acquired via
* <mf IDirectInputDevice::Acquire>.
*
* Note that no guarantees
* are made on the order in which the individual data
* elements are sent. However, data sent by
* successive calls to
* <mf IDirectInputDevice8::SendDeviceData>
* will not be interleaved.
* Furthermore, if multiple pieces of
* data are sent to the same object, it is unspecified
* which actual piece of data is sent.
*
* Consider, for example, a device which can be sent
* data in packets, each packet describing two pieces
* of information, call them A and B. Suppose the
* application attempts to send three data elements,
* "B = 2", "A = 1", and "B = 0".
*
* The actual device will be sent a single packet.
* The "A" field of the packet will contain the value 1,
* and the "B" field of the packet will be either 2 or 0.
*
* If the application wishes the data to be sent to the
* device exactly as specified, then three calls to
* <mf IDirectInputDevice8::SendDeviceData> should be
* performed, each call sending one data element.
*
* In response to the first call,
* the device will be sent a packet where the "A" field
* is blank and the "B" field contains the value 2.
*
* In response to the second call,
* the device will be sent a packet where the "A" field
* contains the value 1, and the "B" field is blank.
*
* Finally, in response to the third call,
* the device will be sent a packet where the "A" field
* is blank and the "B" field contains the value 0.
*
*

* *<p pdwInOut> elements.
*
* <y Note>: The <e DIDEVICEOBJECTDATA.dwOfs> field of
* the <t DIDEVICEOBJECTDATA> structure must contain the
* device object identifier (as obtained from the
* <e DIDEVICEOBJECTINSTANCE.dwType> field of the
* <t DIDEVICEOBJECTINSTANCE> sturcture) for the device

* Furthermore, the <e DIDEVICEOBJECTDATA.dwTimeStamp>

* <c DISDD_CONTINUE>: If this flag is set, then

* sent device data. Otherwise, the device data sent
* will start from scratch.
*
* For example, suppose a device supports two button outputs,
* call them A and B.
* If an application first calls
* <mf IDirectInputDevice8::SendDeviceData> passing
* "button A pressed", then
* a packet of the form "A pressed, B not pressed" will be
* sent to the device.
* If an application then calls
* <mf IDirectInputDevice8::SendDeviceData> passing
* "button B pressed" and the <c DISDD_CONTINUE> flag, then
* a packet of the form "A pressed, B pressed" will be
* sent to the device.
* However, if the application had not passed the
* <c DISDD_CONTINUE> flag, then the packet sent to the device
