+/** @brief Add a pending associations entry
+ *
+ *  Used when a client wants to create an association between
+ *  2 D-Bus endpoint paths, but one of the paths doesn't exist.
+ *  When the path does show up in D-Bus, if there is a pending
+ *  association then the real association objects can be created.

+ * @param[in] objectPath    - The D-Bus object path that should be an
+ *                            association endpoint but doesn't exist
+ *                            on D-Bus.
+ * @param[in] type          - The association type.  Gets used in the final
+ *                            association path of <objectPath>/<type>.
+ * @param[in] endpointPath  - The D-Bus path on the other side
+ *                            of the association. This path exists.
+ * @param[in] endpointType  - The endpoint association type. Gets used
+ *                            in the final association path of
+ *                            <endpointPath>/<endpointType>.
