IMSVidCtl::get_InputsAvailable method (msvidctl.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 get_InputsAvailable method retrieves the input devices that are available within a specified category.

Syntax

HRESULT get_InputsAvailable(
  [in]  BSTR               CategoryGuid,
  [out] IMSVidInputDevices **pVal
);

Parameters

[in] CategoryGuid

BSTR that specifies the GUID of the category to enumerate.

[out] pVal

Receives an IMSVidInputDevices interface pointer. The caller must release the interface.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

This method is provided for Automation clients. C++ applications can use the IMSVidCtl::get__InputsAvailable method, which takes a GUID rather than a BSTR value.

If the method succeeds, the IMSVidInputDevices interface has an outstanding reference count. The caller must release the interface.
