120 This enum is used by the permission() function to report the -

121 permissions and ownership of a file. The values may be OR-ed -

122 together to test multiple permissions and ownership values. -

123 -

124 \value ReadOwner The file is readable by the owner of the file. -

125 \value WriteOwner The file is writable by the owner of the file. -

127 \value ReadUser The file is readable by the user. -

128 \value WriteUser The file is writable by the user. -

129 \value ExeUser The file is executable by the user. -

130 \value ReadGroup The file is readable by the group. -

131 \value WriteGroup The file is writable by the group. -

132 \value ExeGroup The file is executable by the group. -

133 \value ReadOther The file is readable by anyone. -

134 \value WriteOther The file is writable by anyone. -

135 \value ExeOther The file is executable by anyone. -

136 -

137 \warning Because of differences in the platforms supported by Qt, -

138 the semantics of ReadUser, WriteUser and ExeUser are -

139 platform-dependent: On Unix, the rights of the owner of the file -

140 are returned and on Windows the rights of the current user are -

141 returned. This behavior might change in a future Qt version. -

142 -

143 \note On NTFS file systems, ownership and permissions checking is -

144 disabled by default for performance reasons. To enable it, -

145 include the following line: -

149 Permission checking is then turned on and off by incrementing and -

150 decrementing \c qt_ntfs_permission_lookup by 1. -

163 -

164 \ingroup io -

165 -

166 \reentrant -

167 -

168 QFileDevice is the base class for I/O devices that can read and write text and binary files -

169 and \l{The Qt Resource System}{resources}. QFile offers the main functionality, -

170 QFileDevice serves as a base class for sharing functionality with other file devices such -

171 as QTemporaryFile, by providing all the operations that can be done on files that have -

172 been opened by QFile or QTemporaryFile. -

177 /*! -

178 \enum QFileDevice::FileHandleFlag -

179 -

180 This enum is used when opening a file to specify additional -

181 options which only apply to files and not to a generic -

182 QIODevice. -

183 -

184 \value AutoCloseHandle The file handle passed into open() should be -

185 closed by close(), the default behavior is that close just flushes -

186 the file and the application is responsible for closing the file handle. -

187 When opening a file by name, this flag is ignored as Qt always owns the -

188 file handle and must close it. -

189 \value DontCloseHandle If not explicitly closed, the underlying file -

190 handle is left open when the QFile object is destroyed. -
