<hr><a name="details"></a><h2>Detailed Description</h2>
The QHostAddress 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> QHostAddress is normally used with the classes <a href="qsocket.html">QSocket</a>, <a href="qserversocket.html">QServerSocket</a> and
<a href="qsocketdevice.html">QSocketDevice</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">QSocket</a>, <a href="qserversocket.html">QServerSocket</a>, <a href="qsocketdevice.html">QSocketDevice</a> and <a href="io.html">Input/Output and Networking</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QHostAddress"></a>QHostAddress::QHostAddress ()
</h3>
Creates a host address object with the IP address 0.0.0.0.
<h3 class=fn><a name="QHostAddress-2"></a>QHostAddress::QHostAddress ( Q_UINT32 ip4Addr )
</h3>
Creates a host address object for the IPv4 address <em>ip4Addr</em>.
<h3 class=fn><a name="QHostAddress-3"></a>QHostAddress::QHostAddress ( Q_UINT8 * 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="QHostAddress-4"></a>QHostAddress::QHostAddress ( const <a href="qhostaddress.html">QHostAddress</a> & address )
</h3>
Creates a copy of <em>address</em>.
<h3 class=fn><a name="~QHostAddress"></a>QHostAddress::~QHostAddress ()<tt> [virtual]</tt>
</h3>
Destroys the host address object.
<h3 class=fn>Q_UINT32 <a name="ip4Addr"></a>QHostAddress::ip4Addr () 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 (hex: 7f000001).
<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>bool <a name="isIp4Addr"></a>QHostAddress::isIp4Addr () const
</h3>
Returns TRUE if the host address represents a IPv4 address;
otherwise returns FALSE.
<h3 class=fn><a href="qhostaddress.html">QHostAddress</a> & <a name="operator-eq"></a>QHostAddress::operator= ( const <a href="qhostaddress.html">QHostAddress</a> & 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>QHostAddress::operator== ( const <a href="qhostaddress.html">QHostAddress</a> & 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>QHostAddress::setAddress ( Q_UINT32 ip4Addr )
</h3>
Set the IPv4 address specified by <em>ip4Addr</em>.
<h3 class=fn>void <a name="setAddress-2"></a>QHostAddress::setAddress ( Q_UINT8 * 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>QHostAddress::setAddress ( const <a href="qstring.html">QString</a> & 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><a href="qstring.html">QString</a> <a name="toString"></a>QHostAddress::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>().
