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 = "ntqsocket.html" > TQSocket< / a > ,
< a href = "ntqserversocket.html" > TQServerSocket< / a > and < a href = "ntqsocketdevice.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 = "ntqsocket.html" > TQSocket< / a > , < a href = "ntqserversocket.html" > TQServerSocket< / a > , < a href = "ntqsocketdevice.html" > TQSocketDevice< / a > , and < a href = "io.html" > Input/Output and Networking< / a > .

< 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 ( TQ_UINT32 ip4Addr )
< / h3 >
Creates a host address object for the IPv4 address < em > ip4Addr< / em > .
< h3 class = fn > < a name = "TQHostAddress-3" > < / a > TQHostAddress::TQHostAddress ( TQ_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 = "TQHostAddress-4" > < / a > TQHostAddress::TQHostAddress ( const Q_IPV6ADDR & 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 < a href = "ntqhostaddress.html" > TQHostAddress< / a > & 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 > TQ_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 This function is obsolete.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 = "ntqhostaddress.html" > TQHostAddress< / a > & < a name = "operator-eq" > < / a > TQHostAddress::operator= ( const < a href = "ntqhostaddress.html" > TQHostAddress< / 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 > TQHostAddress::operator== ( const < a href = "ntqhostaddress.html" > TQHostAddress< / 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 > TQHostAddress::setAddress ( TQ_UINT32 ip4Addr )
< / h3 >
Set the IPv4 address specified by < em > ip4Addr< / em > .
< h3 class = fn > void < a name = "setAddress-2" > < / a > TQHostAddress::setAddress ( TQ_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 > TQHostAddress::setAddress ( const < a href = "tqstring.html" > TQString< / 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 > TQ_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 < 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 = "tqstring.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 > ().
