DESCRIPTIONA device driver may register a listener that will be notified each time a name lookup on the devfs(5) mount point fails to find the vnode. A listener shall be registered for the dev_clone event. When called, it is supplied with the first argument arg that was specified at handler registration time, appropriate credentials cr, and a name name of length namelen that we look for. If the handler decides that the name is appropriate and wants to create the device that will be associated with the name, it should return it to devfs in the dev argument.The SEE ALSOdevfs(5), namei(9)
