3:
4: Windows toplevel and functions for communication, error-handling.
5: WinMain() is the common toplevel function for several asir variants.
6: 'Main()' (the toplevel of the usual asir session) is called from WinMain().
7: Furthermore, a special GUI for debugging is created by create_debug_gui().
8:
9: There are two sets of events:
10: {Notify0, Notify0_Ack, Intr0, Intr0_Ack, Kill}
11: and
12: {DebugNotify, DebugNotify_Ack, DebugIntr, DebugIntr_Ack}.
13: These are used for the communication between Asir GUI and engine,
14: or debug GUI and engine respectively.
15:
16: Asir GUI <-- Notify0, Notify0_Ack, Kill --> engine
17: debug GUI <-- DebugNotify, DebugNotify_Ack --> engine
