Function rt_object_allocate

src/object.c:477–550

* @brief This function will allocate an object from object system. * * @param type Type of object. The type of the allocated object can only be of * type rt_object_class_type other than RT_Object_Class_Static. * In addition, the type of object allocated through this interface * is dynamic, not static. * * @param name Name of the object. In system, the obj

 * @return object handle allocated successfully, or RT_NULL if no memory can be allocated.
