-- This package implements Calendar.Time delays using protected objects
-- Note: the compiler generates direct calls to this interface, in the
-- processing of time types.
package Ada.Calendar.Delays is
procedure Delay_For (D : Duration);
-- Delay until an interval of length (at least) D seconds has passed, or
-- the task is aborted to at least the current ATC nesting level. This is
-- an abort completion point. The body of this procedure must perform all
-- the processing required for an abort point.
procedure Delay_Until (T : Time);
-- Delay until Clock has reached (at least) time T, or the task is aborted
-- to at least the current ATC nesting level. The body of this procedure
-- must perform all the processing required for an abort point.
function To_Duration (T : Time) return Duration;
-- Convert Time to Duration
end Ada.Calendar.Delays;
