The parameters to the Windows TAP Real-time Ethernet Driver are setup-specific. The function CreateLinkParmsFromCmdLineTap() in EcSelectLinkLayer.cpp demonstrates how to initialize the Real-time Ethernet Driver instance.

struct EC_T_LINK_PARMS_TAP

Public Members

EC_T_LINK_PARMS linkParms

EC_T_CHAR szAdapterName[EC_TAP_ADAPTER_NAME_SIZE]

Native tap device name, e.g. “tap0” (zero terminated)

EC_T_CHAR szAdapterGuid[EC_TAP_ADAPTER_GUID_SIZE]

GUID of virtual interface to connect (zero terminated)

EC_T_BYTE abyMac[6]

The adapter must be manually installed as described in the OpenVPN’s Windows TAP-driver manual, see https://community.openvpn.net/openvpn/wiki/GettingTapWindows .

While EC-Monitor is connected to the adapter using emllTap, the Master can use it with e.g. emllNdis.
