101 \class QHostInfo -

102 \brief The QHostInfo class provides static functions for host name lookups. -

103 -

104 \reentrant -

105 \inmodule QtNetwork -

106 \ingroup network -

107 -

108 QHostInfo uses the lookup mechanisms provided by the operating -

109 system to find the IP address(es) associated with a host name, -

110 or the host name associated with an IP address. -

111 The class provides two static convenience functions: one that -

112 works asynchronously and emits a signal once the host is found, -

113 and one that blocks and returns a QHostInfo object. -

114 -

115 To look up a host's IP addresses asynchronously, call lookupHost(), -

116 which takes the host name or IP address, a receiver object, and a slot -

117 signature as arguments and returns an ID. You can abort the -

118 lookup by calling abortHostLookup() with the lookup ID. -

119 -

120 Example: -

121 -

122 \snippet code/src_network_kernel_qhostinfo.cpp 0 -

123 -

124 -

125 The slot is invoked when the results are ready. The results are -

126 stored in a QHostInfo object. Call -

127 addresses() to get the list of IP addresses for the host, and -

128 hostName() to get the host name that was looked up. -

129 -

130 If the lookup failed, error() returns the type of error that -

131 occurred. errorString() gives a human-readable description of the -

132 lookup error. -

133 -

134 If you want a blocking lookup, use the QHostInfo::fromName() function: -

135 -

136 \snippet code/src_network_kernel_qhostinfo.cpp 1 -

137 -

138 QHostInfo supports Internationalized Domain Names (IDNs) through the -

139 IDNA and Punycode standards. -

140 -

141 To retrieve the name of the local host, use the static -

142 QHostInfo::localHostName() function. -

143 -

144 \note Since Qt 4.6.1 QHostInfo is using multiple threads for DNS lookup -

145 instead of one dedicated DNS thread. This improves performance, -

146 but also changes the order of signal emissions when using lookupHost() -

147 compared to previous versions of Qt. -

148 \note Since Qt 4.6.3 QHostInfo is using a small internal 60 second DNS cache -

149 for performance improvements. -

150 -

151 \sa QAbstractSocket, {http://www.rfc-editor.org/rfc/rfc3492.txt}{RFC 3492} -

152 */ -

153 -

154 static QBasicAtomicInt theIdCounter = Q_BASIC_ATOMIC_INITIALIZER(1); -

155 -

156 /*! -

157 Looks up the IP address(es) associated with host name \a name, and -

158 returns an ID for the lookup. When the result of the lookup is -

159 ready, the slot or signal \a member in \a receiver is called with -

160 a QHostInfo argument. The QHostInfo object can then be inspected -

161 to get the results of the lookup. -

162 -

163 The lookup is performed by a single function call, for example: -

164 -

165 \snippet code/src_network_kernel_qhostinfo.cpp 2 -

166 -

167 The implementation of the slot prints basic information about the -

168 addresses returned by the lookup, or reports an error if it failed: -

169 -

170 \snippet code/src_network_kernel_qhostinfo.cpp 3 -

171 -

172 If you pass a literal IP address to \a name instead of a host name, -

173 QHostInfo will search for the domain name for the IP (i.e., QHostInfo will -

174 perform a \e reverse lookup). On success, the resulting QHostInfo will -

175 contain both the resolved domain name and IP addresses for the host -

176 name. Example: -

177 -

178 \snippet code/src_network_kernel_qhostinfo.cpp 4 -

179 -

180 \note There is no guarantee on the order the signals will be emitted -

181 if you start multiple requests with lookupHost(). -
