Sorry I'm so late again.
No worries. Thanks for testing !
It doesn't crash, but it does cause an
error:
xemacs-21.4 src/xemacs -vanilla -batch -eval '(mswindows-send-sys-command
#xf030)'
Wrong type argument: console-mswindows-p, #<stream-frame "stream" 0x12c>
xemacs exiting
Same when used in tty. This can be avoided using a frame_type_p test:
if (NILP (frame))
frame = Fselected_frame (Qnil);
if (FRAME_TYPE_P (XFRAME (frame), mswindows))
[...]
Seems to work fine for native windows frames, X11 frames, tty and
batch.
Cool !
The Emacs equivalent, `w32-send-sys-command', also errors when the
frame is a Non-Win32 GUI frame (albeit with the message "Non-W32
frame used").
Perhaps this XEmacs `mswindows-send-sys-command' should do likewise
when the FRAME_TYPE_P test is false ? I'm not sure whether it is
preferable to error or not. Unless anyone else has an opinion it's
your call.
