ITSubStreamControl::get_SubStreams method (tapi3if.h)
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 |
|---|---|
|
Method succeeded. |
|
The pVariant parameter is not a valid pointer. |
|
The call appears to have been shut down. |
|
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.
