It stores both IPv4 and IPv6 addresses in a way that you can easily access on any platform. +.PP +QHostAddress is normally used with the classes QSocket, QServerSocket and QSocketDevice to set up a server or to connect to a host. +.PP +Host addresses may be set with setAddress() and retrieved with ip4Addr() or toString(). +.PP +See also QSocket, QServerSocket, QSocketDevice, and Input/Output and Networking. +.SH MEMBER FUNCTION DOCUMENTATION +.SH "QHostAddress::QHostAddress ()" +Creates a host address object with the IP address 0.0.0.0. +.SH "QHostAddress::QHostAddress ( TQ_UINT32 ip4Addr )" +Creates a host address object for the IPv4 address \fIip4Addr\fR. +.SH "QHostAddress::QHostAddress ( TQ_UINT8 * ip6Addr )" +Creates a host address object with the specified IPv6 address. +.PP +\fIip6Addr\fR must be a 16 byte array in network byte order (high-order byte first). +.SH "QHostAddress::QHostAddress ( const Q_IPV6ADDR & ip6Addr )" +Creates a host address object with the IPv6 address, \fIip6Addr\fR. +.SH "QHostAddress::QHostAddress ( const QHostAddress & address )" +Creates a copy of \fIaddress\fR. +.SH "QHostAddress::~QHostAddress ()\fC [virtual]\fR" +Destroys the host address object. +.SH "TQ_UINT32 QHostAddress::ip4Addr () const" +\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code. +.PP +Use toIPv4Address() instead. +.SH "bool QHostAddress::isIPv4Address () const" +Returns TRUE if the host address represents an IPv4 address; otherwise returns FALSE. +.SH "bool QHostAddress::isIPv6Address () const" +Returns TRUE if the host address represents an IPv6 address; otherwise returns FALSE. +.SH "bool QHostAddress::isIp4Addr () const" +\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code. +.PP +Use isIPv4Address() instead. +.SH "bool QHostAddress::isNull () const" +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. +.SH "QHostAddress & QHostAddress::operator= ( const QHostAddress & address )" +Assigns another host address object \fIaddress\fR to this object and returns a reference to this object. +.SH "bool QHostAddress::operator== ( const QHostAddress & other ) const" +Returns TRUE if this host address is the same as \fIother\fR; otherwise returns FALSE. +.SH "void QHostAddress::setAddress ( TQ_UINT32 ip4Addr )" +Set the IPv4 address specified by \fIip4Addr\fR. +.SH "void QHostAddress::setAddress ( TQ_UINT8 * ip6Addr )" +This is an overloaded member function, provided for convenience. It behaves essentially like the above function. +.PP +Set the IPv6 address specified by \fIip6Addr\fR. +.PP +\fIip6Addr\fR must be a 16 byte array in network byte order (high-order byte first). +.SH "bool QHostAddress::setAddress ( const QString & address )" +This is an overloaded member function, provided for convenience. It behaves essentially like the above function. +.PP +Sets the IPv4 or IPv6 address specified by the string representation \fIaddress\fR (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. +.SH "TQ_UINT32 QHostAddress::toIPv4Address () const" +Returns the IPv4 address as a number. +.PP +For example, if the address is 127.0.0.1, the returned value is 2130706433 (i.e. 0x7f000001). +.PP +This value is only valid when isIp4Addr() returns TRUE. +.PP +See also toString(). +.SH "Q_IPV6ADDR QHostAddress::toIPv6Address () const" +Returns the IPv6 address as a Q_IPV6ADDR structure. The structure consists of 16 unsigned characters. +.PP +.nf +.br + Q_IPV6ADDR addr = hostAddr.ip6Addr(); +.br + // addr.c[] contains 16 unsigned characters +.br +.br + for (int i = 0; i < 16; ++i) { +.br + // process addr.c[i] +.br + } +.br +.fi +.PP +This value is only valid when isIPv6Address() returns TRUE. +.PP +See also toString(). +.SH "QString QHostAddress::toString () const" +Returns the address as a string. +.PP +For example, if the address is the IPv4 address 127.0.0.1, the returned string is "127.0.0.1". +.PP +See also ip4Addr(). + +.SH "SEE ALSO" +.BR http://doc.trolltech.com/ntqhostaddress.html +.BR http://www.trolltech.com/faq/tech.html +.SH COPYRIGHT +Copyright 1992-2007 Trolltech ASA, http://www.trolltech.com.
