-        \o If \a fh does not refer to a regular file, e.g., it is \c stdin,
-           \c stdout, or \c stderr, you may not be able to seek(). size()
-           returns \c 0 in those cases. See QIODevice::isSequential() for
-           more information.
-        \o Since this function opens the file without specifying the file name,
-           you cannot use this QFile with a QFileInfo.

-
-    \a fh must be opened in binary mode (i.e., the mode string must contain
-    'b', as in "rb" or "wb") when accessing files and other random-access
-    devices. Qt will translate the end-of-line characters if you pass
-    QIODevice::Text to \a mode. Sequential devices, such as stdin and stdout,
-    are unaffected by this limitation.
-
-    You need to enable support for console applications in order to use the
-    stdin, stdout and stderr streams at the console. To do this, add the
-    following declaration to your application's project file:

-
-    When a QFile is opened using this function, close() does not
-    actually close the file.
-
-    The QFile that is opened using this function is automatically set
-    to be in raw mode; this means that the file input/output functions
