     \class QFile qfile.h

     \brief The QFile class is an I/O device that operates on files.
 
     \ingroup io
     \mainclass
 
     QFile is an I/O device for reading and writing binary and text
     files. A QFile may be used by itself or more conveniently with a
     QDataStream or QTextStream.
 
     The file name is usually passed in the constructor but can be
     changed with setName(). You can check for a file's existence with
     exists() and remove a file with remove().
 
     The file is opened with open(), closed with close() and flushed
     with flush(). Data is usually read and written using QDataStream
     or QTextStream, but you can read with readBlock() and readLine()
     and write with writeBlock(). QFile also supports getch(),
     ungetch() and putch().
 
     The size of the file is returned by size(). You can get the
     current file position or move to a new file position using the
     at() functions. If you've reached the end of the file, atEnd()
     returns TRUE. The file handle is returned by handle().
 
     Here is a code fragment that uses QTextStream to read a text file
     line by line. It prints each line with a line number.
     \code
     QStringList lines;
     QFile file( "file.txt" );
     if ( file.open( IO_ReadOnly ) ) {
 	QTextStream stream( &file );
 	QString line;
 	int i = 1;
-	while ( !stream.eof() ) {
+	while ( !stream.atEnd() ) {
 	    line = stream.readLine(); // line of text excluding '\n'
 	    printf( "%3d: %s\n", i++, line.latin1() );
 	    lines += line;
 	}
 	file.close();
     }
     \endcode
 
     Writing text is just as easy. The following example shows how to
     write the data we read into the string list from the previous
     example:
     \code
     QFile file( "file.txt" );
     if ( file.open( IO_WriteOnly ) ) {
 	QTextStream stream( &file );
 	for ( QStringList::Iterator it = lines.begin(); it != lines.end(); ++it )
 	    stream << *it << "\n";
 	file.close();
     }
     \endcode
 
     The QFileInfo class holds detailed information about a file, such
     as access permissions, file dates and file types.
 
     The QDir class manages directories and lists of file names.
 
     Qt uses Unicode file names. If you want to do your own I/O on Unix
     systems you may want to use encodeName() (and decodeName()) to
     convert the file name into the local encoding.
