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 associated 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.
