IControlInterface::GetName method (devicetopology.h)
The GetName method gets the friendly name for the audio function that the control interface encapsulates.
Syntax
HRESULT GetName(
[out] LPWSTR *ppwstrName
);
Parameters
[out] ppwstrName
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 code | Description |
|---|---|
|
Pointer ppwstrName is NULL. |
|
Out of memory. |
Remarks
As an example of a friendly name, a subunit with an IAudioPeakMeter interface might have the friendly name "peak meter".
