DRV_GetCalibration

Instructs the pen driver to fill a calibration structure with the current calibration settings. The PDC_INTEGRATED flag is used to determine whether the hardware supports calibration.

One of these values:

DRV_FAILURE	Tablet does not support calibration (not integrated)
DRV_BADPARAM1	The first parameter is not a valid pointer to a block of memory at least sizeof(CALBSTRUCT) in length
DRV_SUCCESS	The calibration structure was successfully filled

lParam1: Far pointer to a calibration structure that is filled if the hardware supports calibration.
lParam2: A far pointer to the PENINFO structure. (For a description of PENINFO, see the Programmer's Guide to Pen Services for Windows 95 or PENWIN.H.)
