rxvt-unicode, version 5.2, is a colour vt102 terminal emulator intended as an xterm(1) replacement for users who do not require features such as Tektronix 4014 emulation and toolkit-style configurability. As a result, rxvt-unicode uses much less swap space -- @@ -513,13 +513,13 @@ secondaryScroll.
-The window will not be destroyed when rxvt exits.
+It might be useful to know that rxvt will not close file
descriptors passed to it (except for stdin/out/err, of course), so you
can use file descriptors to communicate with the programs within the
terminal. This works regardless of wether the -embed option was used or
not.
Here is a short Gtk2-perl snippet that illustrates how this option can be +used (a longer example is in doc/embed):
+
+ my $rxvt = new Gtk2::Socket;
+ $rxvt->signal_connect_after (realize => sub {
+ my $xid = $_[0]->window->get_xid;
+ system "rxvt -embed $xid &";
+ });
+If this switch is given, rxvt will not create any utmp/wtmp +entries and will not tinker with pty/tty permissions - you have to do that +yourself if you want that.
+Here is a example in perl that illustrates how this option can be used (a +longer example is in doc/pty-fd):

+ my $pty = new IO::Pty; + fcntl $pty, F_SETFD, 0; # clear close-on-exec + system "rxvt -pty-fd " . (fileno $pty) . "&"; + close $pty;+
+ # now communicate with rxvt
