ITStreamControl::EnumerateStreams method (tapi3if.h)

  • Article

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
);

This method can return one of these values.
