[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.
