------------------------------------------------------------------------------
-- This is an OS/2 version of this package.
-- This package encapsulates and centralizes information about
-- all uses of interrupts (or signals), including then
-- target-dependent mapping of interrupts (or signals) to exceptions.
-- PLEASE DO NOT add any with-clauses to this package.
-- This is designed to work for both tasking and non-tasking systems,
-- without pulling in any of the tasking support.
-- PLEASE DO NOT remove the Elaborate_Body pragma from this package.
-- Elaboration of this package should happen early, as most other
-- initializations depend on it.
-- Forcing immediate elaboration of the body also helps to enforce
-- the design assumption that this is a second-level
-- package, just one level above System.OS_Interface, with no
-- cross-dependences.
-- PLEASE DO NOT put any subprogram declarations with arguments of
-- type Interrupt_ID into the visible part of this package.
-- The type Interrupt_ID is used to derive the type in Ada.Interrupts,
-- and adding more operations to that type would be illegal according
-- to the Ada Reference Manual. (This is the reason why the signals sets
-- below are implemented as visible arrays rather than functions.)
-- This version is a stub, for systems that
-- do not support interrupts (or signals).
package System.Interrupt_Management is
type Interrupt_ID is new Integer range 0 .. -1;
end System.Interrupt_Management;
