--  This package may be used to intercept the interruption of a running
--  program by the operator typing Control-C, without having to use an Ada
--  interrupt handler protected object.
 
--  This package is currently implemented under Windows and Unix platforms
 
--  Note concerning Unix systems:
 
--  The behavior of this package when using tasking depends on the interaction
--  between sigaction() and the thread library.

   type Handler_Type is access procedure;
   --  Any parameterless library level procedure can be used as a handler.
   --  Handler_Type should not propagate exceptions.

   --  Set up Handler to be called if the operator hits Ctrl-C, instead of the
   --  standard Control-C handler.
