/*! \file isc/portset.h
 * \brief Transport Protocol Port Manipulation Module
 *
 * This module provides simple utilities to handle a set of transport protocol
 * (UDP or TCP) port numbers, e.g., for creating an ACL list.  An isc_portset_t
 * object is an opaque instance of a port set, for which the user can add or
 * remove a specific port or a range of consecutive ports.  This object is
 * expected to be used as a temporary work space only, and does not protect
 * simultaneous access from multiple threads.  Therefore it must not be stored
 * in a place that can be accessed from multiple threads.
