 *  Abstract:
 *
 *      Common header file for IDirectInputDevice implementation.
 *
 *      The original didev.c file was getting too big, so the
 *      stuff that supports IDirectInputEffect has been split out
 *      into didevef.c.  Since both files need to access the
 *      internal structure of an IDirectInputDevice, we need this
 *      common header file.

 *
 *          An array of DWORDs listing the locations (data offsets)
 *          of all the optional POVs that were in the app's requested
 *          data format and which we were unable to satisfy.  We

 *          because most apps are lazy and don't check if the object
 *          actually exists before reading from it.  To keep them safe,
 *          we normally return zeros in nonexistent objects, but for
 *          POVs, the "safe" value is -1, not zero.
