Article
02/22/2024

The get_Streams method creates a collection of media streams currently available on the call. Provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateStreams method.

Syntax

HRESULT get_Streams(
  [out] VARIANT *pVariant
);

Parameters

[out] pVariant

Pointer to VARIANT containing an ITCollection of ITStream interface pointers.

Return value

This method can return one of these values.

Value	Meaning
S_OK	Method succeeded.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.
E_POINTER	The pVariant parameter is not a valid pointer.

Remarks

TAPI calls the AddRef method on the ITStream interface returned by ITStreamControl::get_Stream. The application must call Release on the ITStream interface to free resources associated with it.
