BdaCreateTopology function (bdasup.h)

The BdaCreateTopology function creates the topology between two pins.

Syntax

NTSTATUS BdaCreateTopology(
  [in] PKSFILTER pKSFilter,
  [in] ULONG     InputPinId,
  [in] ULONG     OutputPinId
);

Parameters

[in] pKSFilter

Points to the BDA filter on which to create topology.

[in] InputPinId

Specifies the identifier of the filter's input pin.

[in] OutputPinId

Specifies the identifier of the filter's output pin.

Return value

Returns STATUS_SUCCESS or an appropriate error code. Returns NULL if no valid pin pairing exists with the specified input and output pins.

Remarks

A BDA minidriver calls the BdaMethodCreateTopology function when the network provider dynamically creates a topology between filter pins using the KSMETHOD_BDA_CREATE_TOPOLOGY request of the KSMETHODSETID_BdaDeviceConfiguration method set. If a BDA minidriver must create a topology between filter pins without relying on the network provider, the BDA minidriver should call the BdaCreateTopology function directly.
