-- 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).
