<p>Flags for the reverse resolution. </p>
<p>These flags are used by the reverse resolution functions for setting resolution parameters. The possible values are: </p>
<ul>
<li>NumericHost: don't try to resolve the host address to a text form. Instead, convert the address to its numeric textual representation. </li>
<li>NumericService: the same as NumericHost, but for the service name </li>
<li>NodeNameOnly: returns the node name only (i.e., not the Fully Qualified Domain Name) </li>
<li>Datagram: in case of ambiguity in the service name, prefer the name associated with the datagram protocol </li>
<li>NumericScope: for those addresses which have the concept of scope, resolve using the numeric value instead of the proper scope name. </li>
<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 with error instead. </li>
