DESCRIPTION

       The QHostAddress class provides an IP address.

       This class contains an IP address in a platform- and
       protocol-independent manner. That is, it'll store the
       address in a way you can access easily on any platform,
       and it'll store both IPv4 and IPv6 addresses.

       QHostAddress is normally used with the classes QSocket,
       QServerSocket and QSocketDevice to set up a server or to
       connect to a host.

       See also QSocket, QServerSocket and QSocketDevice.


MEMBER FUNCTION DOCUMENTATION


QHostAddress::QHostAddress ()

       Creates a socket address object with the IP address
       0.0.0.0.


QHostAddress::QHostAddress ( Q_UINT32 ip4Addr )

       Creates a socket address object with a specified IPv4
       address.


QHostAddress::QHostAddress ( Q_UINT8 * ip6Addr )

       Creates a socket address object with a specified IPv6
       address.

       ip6Addr must be a 16 byte array in network byte order
       (high-order byte first).


QHostAddress::QHostAddress ( const QHostAddress & address )

       Creates a copy of address.

       Destructs the socket address object.


Q_UINT32 QHostAddress::ip4Addr () const

       Returns the IPv4 address as a number.

       For example, if the address is 127.0.0.1, the returned
       value is 2130706433 (hex: 7f000001).

       This value is only valid when isIp4Addr() returns TRUE.

       See also toString().


bool QHostAddress::isIp4Addr () const

       Return true if the host address represents a IPv4 address.


QHostAddress & QHostAddress::operator= ( const QHostAddress &

       address )
       Assigns another socket address object address to this
       object and returns a reference to this object.


bool QHostAddress::operator== ( const QHostAddress & other )

       const
       Returns TRUE if this socket address is identical to other,
       or FALSE if they are different.


bool QHostAddress::setAddress ( const QString & address )

       Sets the IPv4 or IPv6 address specified by the string
       representation address (e.g. "127.0.0.1").

       If this function is not able to parse the address it will
       return FALSE and the address is not changed.


void QHostAddress::setAddress ( Q_UINT32 ip4Addr )

       Set a IPv4 address specified by ip4Addr.


void QHostAddress::setAddress ( Q_UINT8 * ip6Addr )

       Set a IPv6 address specified by ip6Addr.

       ip6Addr must be a 16 byte array in network byte order
       (high-order byte first).


QString QHostAddress::toString () const

       Returns the address as a string.

       For example, if the address is the IPv4 address 127.0.0.1,
       the returned string is "127.0.0.1".

       See also  ip4Addr().
