[in] IContextNode *pContextNodeToSearchFrom,
[out] IContextNodes **ppContextNodesFound
);
Parameters
-
pCriteria [in]
-
An IMatchesCriteriaCallBack object that is used to evaluate whether an IContextNode object meets or fails its specified criteria.
-
pContextNodeToSearchFrom [in]
-
The IContextNode object whose descendants are searched.

Remarks
Caution
To avoid a memory leak, call IUnknown::Release on ppContextNodesFound when you no longer need to use the object.
If the IInkAnalyzer does not contain the pContextNodeToSearchFrom node, this method returns an error code.
If the IInkAnalyzer contains no such IContextNode, an empty IContextNodes collection is returned.
