NdisMCmOpenAddressFamilyComplete macro

NdisMCmOpenAddressFamilyComplete returns the final status of a client's request, for which the MCM driver's ProtocolCmOpenAf function returned NDIS_STATUS_PENDING, to open the MCM driver's address family.


void NdisMCmOpenAddressFamilyComplete(



Specifies the final status of the client's request to open the AF, either NDIS_STATUS_SUCCESS or any caller-determined NDIS_STATUS_ XXX except NDIS_STATUS_PENDING.


Specifies the NDIS-supplied handle that was input to the MCM driver's ProtocolCmOpenAf function, which returned NDIS_STATUS_PENDING.


Specifies the handle to a caller-allocated resident context area, in which the MCM driver maintains state about this client's open of the address family, including the NdisAfHandle, if the open succeeded. Otherwise, NDIS ignores this parameter.

Return Value



An MCM driver must call NdisMCmOpenAddressFamilyComplete if its ProtocolCmOpenAf function previously returned NDIS_STATUS_PENDING for the given NdisAfHandle . The client, which initiated the pended open-AF operation with a call to NdisClOpenAddressFamilyEx, cannot carry out further connection-oriented operations on the same binding until NdisMCmOpenAddressFamilyComplete causes a call to that client's ProtocolClOpenAfCompleteEx function.

If the caller of NdisMCmOpenAddressFamilyComplete sets Status to NDIS_STATUS_SUCCESS, NDIS subsequently passes the given CallMgrAfContext handle as an input parameter to all MCM driver-supplied ProtocolCmXxx and ProtocolCoXxx functions that concern the client's open of the address family until the client closes the AF. The MCM driver should release or reuse any AF context area that it allocated before it passes a failure status to NdisMCmOpenAddressFamilyComplete.

For a successful open, the NDIS-supplied NdisAfHandle represents an association between the MCM driver and client for the opened AF. Both NDIS drivers must treat NdisAfHandle as an opaque variable to be passed, unmodified and uninterpreted, in subsequent calls to NdisCl/Co/MCm/MCoXxx functions for which this handle is a required parameter. For a failed open, the MCM driver should consider the NdisAfHandle invalid when NdisMCmOpenAddressFamilyComplete returns control.

Only connection-oriented miniport drivers that provide integrated call-management support can call NdisMCmOpenAddressFamilyComplete. Stand-alone call managers, which register themselves with NDIS as protocol drivers, call NdisCmOpenAddressFamilyComplete instead.
