|

|
|
*
|
||
|
|
* A predefined <t DIDATAFORMAT> structure which describes a
|
||
|
|
* keyboard device. This object is provided in the
|
||
|
|
* DINPUT.LIB library file as a convenience.
|
||
|
|
*
|
||
|
|
* A pointer to this structure may be passed to
|
||
|
|
* <mf IDirectInputDevice::SetDataFormat> to indicate that
|
||
|
|
* the device will be accessed in the form of a keyboard.
|
||
|
|
*
|
||
|
|
* When a device has been set to the keyboard data format,
|
||
|
|
* the <mf IDirectInputDevice::GetDeviceState> function
|
||
|
|
* behaves in the same way as the Windows <f GetKeyboardState>
|
||
|
|
* function: The device state is stored in an array of
|
||
|
|
* 256 bytes, with each byte corresponding to the state
|
||
|
|
* of a key. For example, if high bit of the <c DIK_ENTER>'th
|
||
|
|
* byte is set, then the Enter key is being held down.
|
||
|
|
*
|
||
|
|
* When a device has been set to the keyboard data format,
|
||
|
|
* the <mf IDirectInputDevice::GetDeviceData> function
|
||
|
|
* returns a <t DIDEVICEOBJECTDATA> whose <p dwOfs>
|
||
|
|
* field is a <c DIK_*> value which describes the
|
||
|
|
* key which was pressed or released.
