ITStreamControl::get_Streams method (tapi3if.h)
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 |

Method succeeded. |

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.
