2 * Unix PuTTY main program.
17 * - Copy-and-paste from the Event Log.
19 * - Remainder of the context menu:
21 * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
22 * + Duplicate Session will be fun, since we must work out
23 * how to pass the config data through.
24 * + In fact this should be easier on Unix, since fork() is
25 * available so we need not even exec (this also saves us
26 * the trouble of scrabbling around trying to find our own
27 * binary). Possible scenario: respond to Duplicate
28 * Session by forking. Parent continues as before; child
29 * unceremoniously frees all extant resources (backend,
30 * terminal, ldisc, frontend etc) and then _longjmps_ (I
31 * kid you not) back to a point in pt_main() which causes
32 * it to go back round to the point of opening a new
33 * terminal window and a new backend.
34 * + A tricky bit here is how to free everything without
35 * also _destroying_ things - calling GTK to free up
36 * existing widgets is liable to send destroy messages to
37 * the X server, which won't go down too well with the
38 * parent process. exec() is a much cleaner solution to
39 * this bit, but requires us to invent some ghastly IPC as
40 * we did in Windows PuTTY.
41 * + Arrgh! Also, this won't work in pterm since we'll
42 * already have dropped privileges by this point, so we
43 * can't get another pty. Sigh. Looks like exec has to be
44 * the way forward then :-/
46 * - Saved Sessions submenu (not in pterm of course)
48 * - Copy All to Clipboard (for what that's worth)
