This is complicated because dumpcap uses stderr to pipe error messages
to Wireshark, but they have to be in a special format (see source code
comment starting on line 3790 of dumpcap.c in the latest SVN). The
sync_pipe_errmsg_to_parent() function might help you feed an error to
Wireshark, which in theory it will pass through to the user in the GUI.
