kobject_add — the main kobject add function
int kobject_add ( | struct kobject * | kobj, |
| struct kobject * | parent, | |
| const char * | fmt, | |
...); |
kobjthe kobject to add
parentpointer to the parent of the kobject.
fmtformat to name the kobject with.
...variable arguments
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.
