Windows mouse message being queried.

lExtraInfo

Value returned by GetMessageExtraInfo for the given message.

Return Value

Comments

Mouse drivers that have not been updated to be compatible with pens may produce an event that cannot be distinguished from a real pen event. This has a very low probability of occurring.
