KOBJECT_ADD(9) Driver Basics KOBJECT_ADD(9)NAMEkobject_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.
