With Wireshark, I'm trying to modify it to send NDIS requests to a
wifi card driver on windows OS.
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?
To do this I need to call CreateFile() and pass a string of device
name to it.
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.
