KOBJECT_ADD(9)							   Driver Basics						    KOBJECT_ADD(9)

NAME
       kobject_add - the main kobject add function

SYNOPSIS
       int kobject_add(struct kobject * kobj, struct kobject * parent, const char * fmt, ...);

ARGUMENTS
       kobj
	   the kobject to add

       parent
	   pointer to the parent of the kobject.

       fmt
	   format to name the kobject with.

       ...
	   variable arguments

DESCRIPTION
       The kobject name is set and added to the kobject hierarchy in this function.

       If parent is set, then the parent of the kobj will be set to it. If parent is NULL, then the parent of the kobj will be set to the kobject
       associted with the kset assigned to this kobject. If no kset is assigned to the kobject, then the kobject will be located in the root of
       the sysfs tree.

       If this function returns an error, kobject_put must be called to properly clean up the memory associated with the object. Under no instance
       should the kobject that is passed to this function be directly freed with a call to kfree, that can leak memory.

       Note, no "add" uevent will be created with this call, the caller should set up all of the necessary sysfs files for the object and then
       call kobject_uevent with the UEVENT_ADD parameter to ensure that userspace is properly notified of this kobject's creation.
