WebA kobj_type structure describes the type of object that embeds a kobject by means of the ktype field. Every structure that embeds a kobject needs a corresponding kobj_type, which will control what happens when the kobject is created and destroyed, and when attributes are read or written to. Every kobject has a field of the struct kobj_type type ... WebAn attribute definition is simply: struct attribute { char * name; struct module *owner; umode_t mode; }; int sysfs_create_file(struct kobject * kobj, const struct attribute * attr); void sysfs_remove_file(struct kobject * kobj, const struct attribute * attr); A bare attribute contains no means to read or write the value of the attribute.
