Gee, there's a GTK+-based application that does the same thing; you
might have heard of it.... :-)
Look at the source of the "dumpcap" program in Wireshark for an
example of how to do the capture side of that. The secret is that it
doesn't just write to the file and not communicate with the program on
whose behalf it's capturing - every time it writes N packets to the
file, it sends to Wireshark (or TShark) a message over a pipe
indicating that it's written N more packets.
