Detailed Description

The KSaveFile class has been made to write out changes to an existing file atomically. This means that EITHER: a) All changes have been written successfully to the file.

b) Some error occured, no changes have been written whatsoever and the old file is still in place.

The destructor closes the file.

Returns the status of the file based on errno. (see errno.h) 0 means OK.

You should check the status after object creation to check whether a file could be created in the first place.

You may check the status after closing the file to verify that the file has indeed been written correctly.
