+ * from its binary representations into a textual representation.
+ *
+ * Most users will use the static functions @ref resolve, which work
+ * both synchronously (blocking) and asynchronously (non-blocking).

+ * Instead, convert the address to its numeric textual representation.
+ * @li NumericService: the same as NumericHost, but for the service name
+ * @li NodeNameOnly: returns the node name only (i.e., not the Fully
+ * Qualified Domain Name)
+ * @li Datagram: in case of ambiguity in the service name, prefer the
+ * name associated with the datagram protocol
+ * @li NumericScope: for those addresses which have the concept of scope,
+ * resolve using the numeric value instead of the proper scope name.
+ * @li ResolutionRequired: normally, when resolving, if the name resolution
+ * fails, the process normally converts the numeric address into its
+ * presentation forms. This flag causes the function to return
