| Comments
Any symbol can have hot spots, but they are usually of interest only for
gestures. For example, if the user writes "X" for deletion, the center of the "X" its hotspot points to the item to be deleted. Hot spots are returned in tablet
coordinates. The maximum number of hot spots allowed is provided in the PENWIN.H constant
MAXHOTSPOT. The Microsoft Handwriting Recognizer (GRECO.DLL), supports this
function for gesture symbols only.
If cPnts is smaller than the actual number of hot spots, only cPnts points are reported.
