Function rt_object_init

src/object.c:355–432

* @brief This function will initialize an object and add it to object system * management. * * @param object The specified object to be initialized. * The object pointer that needs to be initialized must point to * a specific object memory block, not a null pointer or a wild pointer. * * @param type The object type. The type of the object must be a enumera

 *             uses '\0' as a terminal symbol.
