--  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;
