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.
