Queries the next matching port on the client specified in <em>info</em> argument. The search begins at the next port specified in port field of <em>info</em> argument. For finding the first port at a certain client, give -1.<p>
If a matching port is found, its attributes are stored on <em>info</em> and function returns zero. Otherwise, a negative error code is returned.<p>
