-- 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 abortion 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 abortion point.
function To_Duration (T : Time) return Duration;
end Ada.Calendar.Delays;
