This function signals Card Services to issue a series of callback events as it negotiates for approval with each registered driver. First, Card Services sends a CE_EXCLUSIVE_REQUEST event code to all registered drivers to determine if they allow exclusive use. If all drivers approve the request, Card Services sends each driver a CE_CARD_REMOVAL event code. Finally, it sends a CE_CARD_INSERTION event code to the requesting driver followed by a CE_EXCLUSIVE_COMPLETE event code. If any drivers do not approve, Card Services sends the requesting driver a CE_EXCLUSIVE_COMPLETE event code with a failing status in the Parm1member of the CARD_EVENT_PARMSstructure.
