package System.Tasking.Abortion is
procedure Abort_Tasks (Tasks : Task_List);
-- Abort_Tasks is called to initiate abortion, however, the actual
-- abortion is done by abortee by means of Abort_Handler
procedure Change_Base_Priority (T : Task_ID);
-- Change the base priority of T.
-- Has to be called with T.Lock write locked.
procedure Defer_Abortion;
-- Defer the affects of low-level abortion in the calling task until a
-- matching Undefer_Abortion call is executed. Defer_Abortion can be
-- nested; abortion will be deferred until the calling task has
-- called Undefer_Abortion for each outstanding call to
-- Defer_Abortion. Note that abortion must be deferred before
-- calling any low-level (GNULLI) services.
pragma Inline (Defer_Abortion);
procedure Undefer_Abortion;
-- Undo the effects of one call to Defer_Abortion. When the calling
-- task has called Undefer_Abortion for each outstanding call to
-- Defer_Abortion, any pending low-level abortion will take effect,
-- and subsequent low-level abortions will have an immediate
-- asynchronous effect.
