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

163 been opened by QFile or QTemporaryFile.-

169 \enum QFileDevice::FileHandleFlag-

171 This enum is used when opening a file to specify additional-
172 options which only apply to files and not to a generic-
173 QIODevice.-
174-
175 \value AutoCloseHandle The file handle passed into open() should be-
176 closed by close(), the default behavior is that close just flushes-
177 the file and the application is responsible for closing the file handle.-
178 When opening a file by name, this flag is ignored as Qt always owns the-
179 file handle and must close it.-
180 \value DontCloseHandle If not explicitly closed, the underlying file-
181 handle is left open when the QFile object is destroyed.-
