Description:

		This attribute is provided by the iio-trig-sysfs stand-alone

		driver and it is used to activate the creation of a new trigger.

		In order to achieve this, one should write a positive integer

		into the associated file, which will serve as the id of the

		trigger. If the trigger with the specified id is already present

		in the system, an invalid argument message will be returned.
