IBDA_Topology::SetMedium method (bdaiface.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The SetMedium method configures the medium on which a particular pin sends data.
Syntax
HRESULT SetMedium(
[in] ULONG ulPinId,
[in] REGPINMEDIUM *pMedium
);
Parameters
[in] ulPinId
Specifies the identifier of the pin on which to set the medium.
[in] pMedium
Pointer to the medium on which the pin will send data.
Return value
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
Remarks
A medium is a structure that identifies a hardware data path between two devices on the host system. They can be devices on the same card, such as a crossbar and a tuner on a TV card; devices on separate cards; or external devices. Kernel-mode filters based on the Windows Driver Model can use mediums instead of media types to determine pin connections.
