27
28 - DWORD HandlerRoutine (DWORD dwCtrlType)
29 basically an exception handler routine. handles a few signals / excpts.
30 should be somewhere near the exception handling code ... :)
31
32 Hmm, however as PM applications don't really get a ctrl-c signal,
33 I'll have to do this on my own ...
34
35 - supply unicode<->ascii conversions for all the _A and _W function pairs.
36
37 - problem: we can't prevent thread1 from blocking the message queue ?
38 what will happen if a WinTerminate() is issued there ?
39 will the message queue be closed and provide smooth tasking ?
40 how will open32 react on this ?
41
42 - ECHO_LINE_INPUT / ReadFile blocks till CR
43
44 - scrollbars
45 * do some flowchart to exactly determine WHEN to use WHICH setting
46 and perform WHAT action
47
48 - clipboard support
