Ideally, Wireshark shouldn't do that; all operations on capture
devices should be done through libpcap/WinPcap.
However, as not all the functionality that Wireshark can use is yet
implemented by libpcap/WinPcap APIs, sometimes Wireshark has to
implement that itself. What is it you're trying to do?

That's not necessarily the case.
See, for example, gtk/capture_if_details_dlg_win32.c, which makes
calls to wpcap_packet_request_uint() to fetch various statistics and
other information about a network adapter. It calls wpcap_packet_open
() to get a lower-level handle on the device.
Those routines are in capture_wpcap_packet.c, which provides access to
the Packet Driver API in Winpcap; the routines from that file might be
sufficient to do what you want.
Yeah, this seems to be what I'm looking for. I'll try it out.
Many thanks,
Joshua
