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