IControlInterface::GetName method

The GetName method gets the friendly name for the audio function that the control interface encapsulates.

Syntax


HRESULT GetName(
  [out] LPWSTR *ppwstrName
);

Parameters

ppwstrName [out]

Pointer to a string pointer into which the method writes the address of a null-terminated, wide-character string that contains the friendly name. The method allocates the storage for the string. The caller is responsible for freeing the storage, when it is no longer needed, by calling the CoTaskMemFree function. If the GetName call fails, *ppwstrName is NULL. For information about CoTaskMemFree, see the Windows SDK documentation.

Return value

If the method succeeds, it returns S_OK. If it fails, possible return codes include, but are not limited to, the values shown in the following table.

Return codeDescription
