60 * @brief This file contains all of the method and constants associated with
61 * the SCI base object. The SCI base object is the class from which
62 * all other objects derive in the Storage Controller Interface.

73 * @brief This method returns the object to which a previous association was
74 * created. This association represents a link between an SCI object
75 * and another SCI object or potentially a user object. The
76 * association essentially acts as a cookie for the user of an object.
77 * The user of an SCI object is now able to retrieve a handle to their
78 * own object that is managing, or related in someway, to said SCI
81 * @param[in] base_object This parameter specifies the SCI object for
82 * which to retrieve the association reference.
84 * @return This method returns a pointer to the object that was previously
85 * associated to the supplied base_object parameter.
86 * @retval SCI_INVALID_HANDLE This value is returned when there is no known
87 * association for the supplied base_object instance.

104 * which to set the association reference.
105 * @param[in] associated_object This parameter specifies a pointer to the
106 * object being associated.
108 * @return This method will return an indication as to whether the
109 * association was set successfully.
110 * @retval SCI_SUCCESS This value is currently always returned.
