378
379Tells @@RXVT_NAME@@ to embed it's windows into an already-existing window,
380which enables applications to easily embed a terminal.
381
382Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
383shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
384quite a bit, so don't expect it to keep some specific state. It's best to
385create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
386
387The window will not be destroyed when @@RXVT_NAME@@ exits.
388
389It might be useful to know that @@RXVT_NAME@@ will not close file
390descriptors passed to it (except for stdin/out/err, of course), so you
391can use file descriptors to communicate with the programs within the
392terminal. This works regardless of wether the C<-embed> option was used or
393not.
394
395Here is a short Gtk2-perl snippet that illustrates how this option can be
396used (a longer example is in F<doc/embed>):
397
398 my $rxvt = new Gtk2::Socket;
399 $rxvt->signal_connect_after (realize => sub {
400 my $xid = $_[0]->window->get_xid;
401 system "@@RXVT_NAME@@ -embed $xid &";
402 });
403
404=item B<-pty-fd> I<fileno>
405
406Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
407pair but instead use the given filehandle as the tty master. This is
408useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
409without having to run a program within it.
410
411If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
412entries and will not tinker with pty/tty permissions - you have to do that
413yourself if you want that.
414
415Here is a example in perl that illustrates how this option can be used (a
416longer example is in F<doc/pty-fd>):
417
418 use IO::Pty;
419 use Fcntl;
420
421 my $pty = new IO::Pty;
422 fcntl $pty, F_SETFD, 0; # clear close-on-exec
423 system "@@RXVT_NAME@@ -pty-fd " . (fileno $pty) . "&";
424 close $pty;
425
426 # now communicate with rxvt
427 my $slave = $pty->slave;
428 while (<$slave>) { print $slave "got <$_>\n" }
