+Description:
+               The name attribute holds a description string for the current
+               trigger. In order to associate the trigger with an IIO device
+               one should write this name string to
+               /sys/bus/iio/devices/iio:deviceY/trigger/current_trigger.

+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.

+Description:
+               This attribute is used to unregister and delete a previously
+               created trigger from the list of available triggers. In order to
+               achieve this, one should write a positive integer into the
+               associated file, representing the id of the trigger that needs
+               to be removed. If the trigger can't be found, an invalid
+               argument message will be returned to the user.
