-- Simple task lock and unlock routines
-- A small package containing a task lock and unlock routines for creating
-- a critical region. The lock involved is a global lock, shared by all
-- tasks, and by all calls to these routines, so these routines should be
-- used with care to avoid unnecessary reduction of concurrency.
-- These routines may be used in a non-tasking program, and in that case
-- they have no effect (they do NOT cause the tasking runtime to be loaded).
-- See file s-tasloc.ads for full documentation of the interface
with System.Task_Lock;
package GNAT.Task_Lock renames System.Task_Lock;
