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 * - Remainder of the context menu:
25 * - Event Log (this means we must implement the Event Log; not
28 * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
29 * + Duplicate Session will be fun, since we must work out
30 * how to pass the config data through.
31 * + In fact this should be easier on Unix, since fork() is
32 * available so we need not even exec (this also saves us
33 * the trouble of scrabbling around trying to find our own
34 * binary). Possible scenario: respond to Duplicate
35 * Session by forking. Parent continues as before; child
36 * unceremoniously frees all extant resources (backend,
37 * terminal, ldisc, frontend etc) and then _longjmps_ (I
38 * kid you not) back to a point in pt_main() which causes
39 * it to go back round to the point of opening a new
40 * terminal window and a new backend.
41 * + A tricky bit here is how to free everything without
42 * also _destroying_ things - calling GTK to free up
43 * existing widgets is liable to send destroy messages to
44 * the X server, which won't go down too well with the
45 * parent process. exec() is a much cleaner solution to
46 * this bit, but requires us to invent some ghastly IPC as
47 * we did in Windows PuTTY.
48 * + Arrgh! Also, this won't work in pterm since we'll
49 * already have dropped privileges by this point, so we
50 * can't get another pty. Sigh. Looks like exec has to be
51 * the way forward then :-/
53 * - Saved Sessions submenu (not in pterm of course)
56 * + we must also implement mid-session reconfig in pterm.c.
57 * + note this also requires config.c and uxcfg.c to be able
58 * to get hold of the application name.
60 * - Copy All to Clipboard (for what that's worth)
66 void cleanup_exit(int code)
77 * Another bunch of temporary stub functions. These ones will want
78 * removing by means of implementing them properly: libcharset
79 * should invent its own sensible format for codepage names and a
80 * means of enumerating them, and printer_enum needs to be dealt
81 * with somehow or other too.
