DEV_CLONE(9) BSD Kernel Developer's Manual DEV_CLONE(9)NAME
dev_clone, drain_dev_clone_events -- eventhandler for name-based device cloning in devfs
SYNOPSIS
#include <sys/param.h>
#include <sys/conf.h>
void
clone_handler(void *arg, struct ucred *cr, char *name, int namelen, struct cdev **dev);
EVENTHANDLER_REGISTER(dev_clone, clone_handler, arg, priority);
void
drain_dev_clone_events();
DESCRIPTION
A 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 drain_dev_clone_events() function is a barrier. It is guaranteed that all calls to eventhandlers for dev_clone that were started before
drain_dev_clone_events() call, are finished before it returns control.
