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

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

53 -- standard Control-C handler.
55 procedure Uninstall_Handler;
