IWTTLog::CloseLogDevice
The CloseLogDevice method closes a log device topology that the device string or the handle specifies.
HRESULT CloseLogDevice (
BSTR bstrLogDeviceName,
LONG hDevice
);
Parameters
bstrLogDeviceName
[in] A log device string, which has the following syntax.
$<device_type>:<parameter_list>($<child_device1>[; $<child_device2>; ...])
For more information about constructing a device string, see Device String.
hDevice
[in] A handle to the device tracing topology. You can combine multiple handles by using the bitwise OR operator (for example, hDevice1 OR hDevice2).
Return Value
CloseLogDevice returns one of the following values:
- S_OK
The operation was successful. - S_FALSE
The operation was successful but the last device has been detached, which has triggered a rollup. - HRESULT
The operation failed. You should use the FAILED macro to check HRESULT values.
Comments
If a handle is specified in the hDevice parameter, the device string in the bstrLogDeviceName parameter is ignored.
