Determines hardware calibration information and puts it into a DRV_CALBSTRUCT structure provided by the caller.
lParam1
Pointer to the DRV_CALBSTRUCT structure where the virtual pen driver must put the current calibration information.
lParam2
Should be set to zero.
For a definition of the members of the DRV_CALBSTRUCT structure see the "Reference" section in About the Pen Driver.
The VPEND_GETCALIBRATION message is sent by the pen driver code that handles the DRV_LOAD message, which is sent to the pen driver when the system loads it. Note that the pen driver code that handles the DRV_GetCalibration message does not send a VPEND_GETCALIBRATION message to the virtual pen driver; the pen driver handles the DRV_GetCalibration message itself by getting information out of the DRV_CALBSTRUCT structure.
