\class QSaveFile
\brief The QSaveFile class provides an interface for safely writing to files.
\ingroup io
\reentrant
QSaveFile is an I/O device for writing text and binary files, without losing
existing data if the writing operation fails.
While writing, the contents will be written to a temporary file, and if
no error happened, commit() will move it to the final file. This ensures that
no data at the final file is lost in case an error happens while writing,
and no partially-written file is ever present at the final location. Always
use QSaveFile when saving entire documents to disk.
QSaveFile automatically detects errors while writing, such as the full partition
situation, where write() cannot write all the bytes. It will remember that
an error happened, and will discard the temporary file in commit().
Much like with QFile, the file is opened with open(). Data is usually read
and written using QDataStream or QTextStream, but you can also call the
QIODevice-inherited functions read(), readLine(), readAll(), write().
Unlike QFile, calling close() is not allowed. commit() replaces it. If commit()
was not called and the QSaveFile instance is destroyed, the temporary file is
discarded.
