IBDA_Topology::GetNodeTypes method (bdaiface.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The GetNodeTypes method retrieves a list of all the node types in the template topology for this filter and network type.
Syntax
HRESULT GetNodeTypes(
[out] ULONG *pulcNodeTypes,
[in] ULONG ulcNodeTypesMax,
[out] ULONG [] rgulNodeTypes
);
Parameters
[out] pulcNodeTypes
Pointer that receives the number of node types in the list.
[in] ulcNodeTypesMax
The maximum number of node types that can be held by the rgulNodeTypes buffer.
[out] rgulNodeTypes
Pointer to a buffer that receives the list of node types.
Return value
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
The IBDA_Topology interface is implemented by a BDA Device Filter. It is used by a Network Provider to query a BDA Device Filter's possible topologies (template topology) and to configure the device with an appropriate topology for the current tuning request. It is also used to get an IUnknown to a control node which may be used to set specific tuning information.
