Article
10/13/2021

The get_SubStreams method creates a collection of substreams currently available. Provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateSubStreams method.

Syntax

HRESULT get_SubStreams(
  [out] VARIANT *pVariant
);

Parameters

[out] pVariant

Pointer to VARIANT containing an ITCollection of ITSubStream interface pointers.

Return value

This method can return one of these values.

Value	Meaning
S_OK	Method succeeded.
E_POINTER	The pVariant parameter is not a valid pointer.
E_UNEXPECTED	The call appears to have been shut down.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.

Remarks

TAPI calls the AddRef method on the ITSubStream interface returned by ITSubStreamControl::get_SubStreams. The application must call Release on the ITSubStream interface to free resources associated with it.
