2 * Unix PuTTY main program.
17 * - libcharset enumeration.
19 * - fix the printer enum (I think the sensible thing is simply to
20 * have uxcfg.c remove the drop-down list completely, since you
21 * can't sensibly provide an enumerated list of lpr commands!).
23 * - Ctrl+right-click for a context menu (also in Windows for
24 * consistency, I think). This should contain pretty much
25 * everything in the Windows PuTTY menu, and a subset of that in
28 * - Telnet special commands (not in pterm :-)
30 * - Event Log (this means we must implement the Event Log; not
33 * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
34 * + Duplicate Session will be fun, since we must work out
35 * how to pass the config data through.
36 * + In fact this should be easier on Unix, since fork() is
37 * available so we need not even exec (this also saves us
38 * the trouble of scrabbling around trying to find our own
39 * binary). Possible scenario: respond to Duplicate
40 * Session by forking. Parent continues as before; child
41 * unceremoniously frees all extant resources (backend,
42 * terminal, ldisc, frontend etc) and then _longjmps_ (I
43 * kid you not) back to a point in pt_main() which causes
44 * it to go back round to the point of opening a new
45 * terminal window and a new backend.
46 * + A tricky bit here is how to free everything without
47 * also _destroying_ things - calling GTK to free up
48 * existing widgets is liable to send destroy messages to
49 * the X server, which won't go down too well with the
50 * parent process. exec() is a much cleaner solution to
51 * this bit, but requires us to invent some ghastly IPC as
52 * we did in Windows PuTTY.
53 * + Arrgh! Also, this won't work in pterm since we'll
54 * already have dropped privileges by this point, so we
55 * can't get another pty. Sigh. Looks like exec has to be
56 * the way forward then :-/
58 * - Saved Sessions submenu (not in pterm of course)
61 * + we must also implement mid-session reconfig in pterm.c.
62 * + note this also requires config.c and uxcfg.c to be able
63 * to get hold of the application name.
65 * - Copy All to Clipboard (for what that's worth)
67 * - Clear Scrollback and Reset Terminal
69 * - About (and uxcfg.c must also supply the about box)
75 void cleanup_exit(int code)
86 * Another bunch of temporary stub functions. These ones will want
87 * removing by means of implementing them properly: libcharset
88 * should invent its own sensible format for codepage names and a
89 * means of enumerating them, and printer_enum needs to be dealt
90 * with somehow or other too.
