23 - DWORD HandlerRoutine (DWORD dwCtrlType)
24 basically an exception handler routine. handles a few signals / excpts.
25 should be somewhere near the exception handling code ... :)
26
27 Hmm, however as PM applications don't really get a ctrl-c signal,
28 I'll have to do this on my own ...
29
30 - supply unicode<->ascii conversions for all the _A and _W function pairs.
31
32 - problem: we can't prevent thread1 from blocking the message queue ?
33 what will happen if a WinTerminate() is issued there ?
34 will the message queue be closed and provide smooth tasking ?
35 how will open32 react on this ?
36
37 - ECHO_LINE_INPUT / ReadFile blocks till CR
38
39 - scrollbars
40 * do some flowchart to exactly determine WHEN to use WHICH setting
41 and perform WHAT action
42
43 - clipboard support
