The EnumerateStreams method enumerates currently available media streams. Provided for C and C++ applications. Automation client applications such as Visual Basic must use the get_Streams method.

Syntax

HRESULT EnumerateStreams(
  [out] IEnumStream **ppEnumStream
);

Parameters

[out] ppEnumStream

Pointer to pointer for IEnumStream enumerator.

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 ppEnumStream parameter is not a valid pointer.

Remarks

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