-- User interface to the interrupt services
--
-- Provides backward compatibility with earlier releases of VADS.
--
-- The interface to ALL the low kernel services is now provided in
-- ada_krn_i.a. Types used by these services is defined in ada_krn_defs.a.
--
-- This package simply layers upon the interrupt data structures and
-- subprograms found in ada_krn_defs.a and ada_krn_i.a.
--
-- Differences from earlier releases:
-- [1] The following services aren't supported: enter_isr(), complete_isr().
