5.21. Windows TAP - emllTap

The parameters to the Windows TAP Link Layer are setup-specific. The function CreateLinkParmsFromCmdLineTap() in EcSelectLinkLayer.cpp demonstrates how to initialize the Link Layer instance.

struct EC_T_LINK_PARMS_TAP

Public Members

EC_T_LINK_PARMS linkParms

Common link parameters. Signature must be set to EC_LINK_PARMS_SIGNATURE_TAP

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]

MAC address

EC_T_DWORD dwRxBufferCnt

Frame buffer count for IST

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