+
+
+The TQHostAddress class provides an IP address.
+
+<p>
+
+<p> This class contains an IP address in a platform and protocol
+independent manner. It stores both IPv4 and IPv6 addresses in a
+way that you can easily access on any platform.
+<p> TQHostAddress is normally used with the classes <a href="qsocket.html">TQSocket</a>,
+<a href="qserversocket.html">TQServerSocket</a> and <a href="qsocketdevice.html">TQSocketDevice</a> to set up a server or to connect
+to a host.
+<p> Host addresses may be set with <a href="#setAddress">setAddress</a>() and retrieved with
+<a href="#ip4Addr">ip4Addr</a>() or <a href="#toString">toString</a>().
+<p> <p>See also <a href="qsocket.html">TQSocket</a>, <a href="qserversocket.html">TQServerSocket</a>, <a href="qsocketdevice.html">TQSocketDevice</a>, and <a href="io.html">Input/Output and Networking</a>.

+<hr><h2>Member Function Documentation</h2>
+<h3 class=fn><a name="TQHostAddress"></a>TQHostAddress::TQHostAddress ()
+</h3>
+Creates a host address object with the IP address 0.0.0.0.
+
+<h3 class=fn><a name="TQHostAddress-2"></a>TQHostAddress::TQHostAddress ( Q_UINT32&nbsp;ip4Addr )
+</h3>
+Creates a host address object for the IPv4 address <em>ip4Addr</em>.
+
+<h3 class=fn><a name="TQHostAddress-3"></a>TQHostAddress::TQHostAddress ( Q_UINT8&nbsp;*&nbsp;ip6Addr )
+</h3>
+Creates a host address object with the specified IPv6 address.
+<p> <em>ip6Addr</em> must be a 16 byte array in network byte order
+(high-order byte first).
+
+<h3 class=fn><a name="TQHostAddress-4"></a>TQHostAddress::TQHostAddress ( const&nbsp;Q_IPV6ADDR&nbsp;&amp;&nbsp;ip6Addr )
+</h3>
+Creates a host address object with the IPv6 address, <em>ip6Addr</em>.
+
+<h3 class=fn><a name="TQHostAddress-6"></a>TQHostAddress::TQHostAddress ( const&nbsp;<a href="qhostaddress.html">TQHostAddress</a>&nbsp;&amp;&nbsp;address )
+</h3>
+Creates a copy of <em>address</em>.
+
+<h3 class=fn><a name="~TQHostAddress"></a>TQHostAddress::~TQHostAddress ()<tt> [virtual]</tt>
+</h3>
+Destroys the host address object.
+
+<h3 class=fn>Q_UINT32 <a name="ip4Addr"></a>TQHostAddress::ip4Addr () const
+</h3>
+<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
+<p> Use <a href="#toIPv4Address">toIPv4Address</a>() instead.
+
+<h3 class=fn>bool <a name="isIPv4Address"></a>TQHostAddress::isIPv4Address () const
+</h3>
+Returns TRUE if the host address represents an IPv4 address;
+otherwise returns FALSE.
+
+<h3 class=fn>bool <a name="isIPv6Address"></a>TQHostAddress::isIPv6Address () const
+</h3>
+Returns TRUE if the host address represents an IPv6 address;
+otherwise returns FALSE.
+
+<h3 class=fn>bool <a name="isIp4Addr"></a>TQHostAddress::isIp4Addr () const
+</h3>
+<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
+<p> Use <a href="#isIPv4Address">isIPv4Address</a>() instead.
+
+<h3 class=fn>bool <a name="isNull"></a>TQHostAddress::isNull () const
+</h3>
+Returns TRUE if this host address is null (INADDR_ANY or in6addr_any). The
+default constructor creates a null address, and that address isn't valid
+for any particular host or interface.
+
+<h3 class=fn><a href="qhostaddress.html">TQHostAddress</a>&nbsp;&amp; <a name="operator-eq"></a>TQHostAddress::operator= ( const&nbsp;<a href="qhostaddress.html">TQHostAddress</a>&nbsp;&amp;&nbsp;address )
+</h3>
+Assigns another host address object <em>address</em> to this object and
+returns a reference to this object.
+
+<h3 class=fn>bool <a name="operator-eq-eq"></a>TQHostAddress::operator== ( const&nbsp;<a href="qhostaddress.html">TQHostAddress</a>&nbsp;&amp;&nbsp;other ) const
+</h3>
+Returns TRUE if this host address is the same as <em>other</em>;
+otherwise returns FALSE.
+
+<h3 class=fn>void <a name="setAddress"></a>TQHostAddress::setAddress ( Q_UINT32&nbsp;ip4Addr )
+</h3>
+Set the IPv4 address specified by <em>ip4Addr</em>.
+
+<h3 class=fn>void <a name="setAddress-2"></a>TQHostAddress::setAddress ( Q_UINT8&nbsp;*&nbsp;ip6Addr )
+</h3>
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+<p> Set the IPv6 address specified by <em>ip6Addr</em>.
+<p> <em>ip6Addr</em> must be a 16 byte array in network byte order
+(high-order byte first).
+
+<h3 class=fn>bool <a name="setAddress-3"></a>TQHostAddress::setAddress ( const&nbsp;<a href="qstring.html">TQString</a>&nbsp;&amp;&nbsp;address )
+</h3>
+This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
+<p> Sets the IPv4 or IPv6 address specified by the string
+representation <em>address</em> (e.g. "127.0.0.1"). Returns TRUE and
+sets the address if the address was successfully parsed; otherwise
+returns FALSE and leaves the address unchanged.
+
+<h3 class=fn>Q_UINT32 <a name="toIPv4Address"></a>TQHostAddress::toIPv4Address () const
+</h3>
+Returns the IPv4 address as a number.
+<p> For example, if the address is 127.0.0.1, the returned value is
+2130706433 (i.e. 0x7f000001).
+<p> This value is only valid when <a href="#isIp4Addr">isIp4Addr</a>() returns TRUE.
+<p> <p>See also <a href="#toString">toString</a>().
+
+<h3 class=fn>Q_IPV6ADDR <a name="toIPv6Address"></a>TQHostAddress::toIPv6Address () const
+</h3>
+Returns the IPv6 address as a Q_IPV6ADDR structure. The structure
+consists of 16 unsigned characters.
+<p> <pre>
+ Q_IPV6ADDR addr = hostAddr.ip6Addr();
+ // addr.c[] contains 16 unsigned characters
+
+ for (int i = 0; i &lt; 16; ++i) {
+ // process addr.c[i]
+ }
+ </pre>
+
+<p> This value is only valid when <a href="#isIPv6Address">isIPv6Address</a>() returns TRUE.
+<p> <p>See also <a href="#toString">toString</a>().
+
+<h3 class=fn><a href="qstring.html">TQString</a> <a name="toString"></a>TQHostAddress::toString () const
+</h3>
+Returns the address as a string.
+<p> For example, if the address is the IPv4 address 127.0.0.1, the
+returned string is "127.0.0.1".
+<p> <p>See also <a href="#ip4Addr">ip4Addr</a>().
