IBDA_Topology::GetNodeTypes Method

2009-01-07

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

pulcNodeTypes [out]
Pointer that receives the number of node types in the list.
ulcNodeTypesMax [in]
The maximum number of node types that can be held by the rgulNodeTypes buffer.
rgulNodeTypes [out]
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.
