.SH DESCRIPTION
|
|
The TQHostAddress class provides an IP address.
|
|
.PP
|
|
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.
|
|
.PP
|
|
TQHostAddress is normally used with the classes TQSocket, TQServerSocket and TQSocketDevice 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 TQSocket, TQServerSocket, TQSocketDevice, and Input/Output and Networking.
|
|
.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "TQHostAddress::TQHostAddress ()"
|
|
Creates a host address object with the IP address 0.0.0.0.
|
|
.SH "TQHostAddress::TQHostAddress ( TQ_UINT32 ip4Addr )"
|
|
Creates a host address object for the IPv4 address \fIip4Addr\fR.
|
|
.SH "TQHostAddress::TQHostAddress ( 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 "TQHostAddress::TQHostAddress ( const Q_IPV6ADDR & ip6Addr )"
|
|
Creates a host address object with the IPv6 address, \fIip6Addr\fR.
|
|
.SH "TQHostAddress::TQHostAddress ( const TQHostAddress & address )"
|
|
Creates a copy of \fIaddress\fR.
|
|
.SH "TQHostAddress::~TQHostAddress ()\fC [virtual]\fR"
|
|
Destroys the host address object.
|
|
.SH "TQ_UINT32 TQHostAddress::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\fBThis function is obsolete.\fR It is provided to keep old source working.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 TQHostAddress::isIPv4Address () const"
|
|
Returns TRUE if the host address represents an IPv4 address; otherwise returns FALSE.
|
|
.SH "bool TQHostAddress::isIPv6Address () const"
|
|
Returns TRUE if the host address represents an IPv6 address; otherwise returns FALSE.
|
|
.SH "bool TQHostAddress::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\fBThis function is obsolete.\fR It is provided to keep old source working.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 TQHostAddress::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 "TQHostAddress & TQHostAddress::operator= ( const TQHostAddress & address )"
|
|
Assigns another host address object \fIaddress\fR to this object and returns a reference to this object.
|
|
.SH "bool TQHostAddress::operator== ( const TQHostAddress & other ) const"
|
|
Returns TRUE if this host address is the same as \fIother\fR; otherwise returns FALSE.
|
|
.SH "void TQHostAddress::setAddress ( TQ_UINT32 ip4Addr )"
|
|
Set the IPv4 address specified by \fIip4Addr\fR.
|
|
.SH "void TQHostAddress::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 TQHostAddress::setAddress ( const TQString & 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 TQHostAddress::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 TQHostAddress::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 "TQString TQHostAddress::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().
