template<typename DEV, typename FACTORY = Simple_factory<DEV>, typename SCHEDULER = Rr_scheduler<typename FACTORY::Device_type>>

int Block_device::Device_mgr< DEV, FACTORY, SCHEDULER >::parse_device_name ( std::string const & param, std::string & device )

inlinestatic

Parse and verify a device string parameter.

Parameters

[in]	param	Device string name parameter.
[out]	device	Device name extracted from parameter.

Returns

L4 error code.

This function tests if 'param' contains one of the following variants of a device name and extracts it into 'device':

• "partlabel:<label>": 'device' contains "<label>" without conversion.

• "partuuid:<uuid>": Check if "<uuid>" is a valid UUID and return with error if not. In case of success, 'device' contains "<uuid>" with all characters converted to upper case.

• "<string>": Check if "<string>" is a valid UUID. If so, 'device' contains "<string>" with all characters converted to upper case. Otherwise, 'device' contains the unmodified "<string>".
