WinPcap questions should be sent to winpcap-users at winpcap.org, not to me.

You should, however, be able to open the two interfaces with
pcap_open(), call pcap_gethandle() to get handles from the two pcap_t's,
and then block on them with a WaitForMultipleEvents() call and, if any
of them are indicated as readable by WaitForMultipleEvents(), call
pcap_dispatch() on them. (On UN*X, you'd use pcap_get_selectable_fd()
or, in older versions, pcap_fileno(), and call select() on them - NOTE
that, at least in Mac OS X 10.4[.x], you can't use poll() on them.)
