-- This package provides users with the ability to use a custom routine for
-- connecting hardware interrupts for VxWorks environments that support the
-- capability to handle them. The custom routine must have the same profile
-- as the VxWorks intConnect() routine.

-- subsequent calls to Attach_Handler.
