The handle to the parent devfs directory entry. If this is NULL the new name is relative to the root of the devfs.
The name of the entry.
An arbitrary pointer which will be associated with the entry.
Use of this function is optional. The devfs_register function will automatically create intermediate directories as needed. This function is provided for efficiency reasons, as it provides a handle to a directory. Returns a handle which may later be used in a call to devfs_unregister. On failure NULL is returned.
