NDIS_MINIPORT_CO_CHARACTERISTICS structure (ndis.h)
The NDIS_MINIPORT_CO_CHARACTERISTICS structure specifies the CoNDIS entry points for a CoNDIS miniport driver.
Syntax
typedef struct _NDIS_MINIPORT_CO_CHARACTERISTICS {
NDIS_OBJECT_HEADER Header;
ULONG Flags;
W_CO_CREATE_VC_HANDLER CoCreateVcHandler;
W_CO_DELETE_VC_HANDLER CoDeleteVcHandler;
W_CO_ACTIVATE_VC_HANDLER CoActivateVcHandler;
W_CO_DEACTIVATE_VC_HANDLER CoDeactivateVcHandler;
W_CO_SEND_NET_BUFFER_LISTS_HANDLER CoSendNetBufferListsHandler;
W_CO_OID_REQUEST_HANDLER CoOidRequestHandler;
} NDIS_MINIPORT_CO_CHARACTERISTICS, *PNDIS_MINIPORT_CO_CHARACTERISTICS;
Members
Header
The
NDIS_OBJECT_HEADER structure for the
miniport driver CoNDIS characteristics structure (NDIS_MINIPORT_CO_CHARACTERISTICS). The driver sets the
Type member of the structure that
Header specifies to NDIS_OBJECT_TYPE_CO_MINIPORT_CHARACTERISTICS, the
Revision member to NDIS_MINIPORT_CO_CHARACTERISTICS_REVISION_1, and the
Size member to NDIS_SIZEOF_MINIPORT_CO_CHARACTERISTICS_REVISION_1.
Flags
Reserved for NDIS.
CoCreateVcHandler
The entry point of the driver's MiniportCoCreateVc function. If this entry point is for an integrated miniport call manager (MCM) driver, this member should be NULL, because NDIS calls such a driver's ProtocolCoCreateVc function instead. For more information about ProtocolCoCreateVc in an MCM, see NDIS_CO_CALL_MANAGER_OPTIONAL_HANDLERS.
CoDeleteVcHandler
The entry point of the driver's MiniportCoDeleteVc function. If this entry point is for an integrated miniport call manager (MCM) driver, this member should be NULL, because NDIS calls such a driver's ProtocolCoDeleteVc function instead. For more information about ProtocolCoDeleteVc in an MCM, see NDIS_CO_CALL_MANAGER_OPTIONAL_HANDLERS.
CoActivateVcHandler
The entry point of the driver's MiniportCoActivateVc function.
CoDeactivateVcHandler
The entry point of the driver's MiniportCoDeactivateVc function.
CoSendNetBufferListsHandler
The entry point of the driver's MiniportCoSendNetBufferLists function.
CoOidRequestHandler
The entry point of the driver's MiniportCoOidRequest function.
Remarks
To specify entry points for CoNDIS, a miniport driver initializes an NDIS_MINIPORT_CO_CHARACTERISTICS structure and passes it to the NdisSetOptionalHandlers function.
The miniport driver calls NdisSetOptionalHandlers from the MiniportSetOptions function.
