Returns an output stream for overwriting the file in readwrite mode,
possibly creating a backup copy of the file first. If the file doesn't
exist, it will be created.

For details about the behaviour, see g_file_replace() which does the
same thing but returns an output stream only.

Note that in many non-local file cases read and write streams are not
supported, so make sure you really need to do read and write streaming,
rather than just opening for reading or writing.

(transfer full): a #GFileIOStream or %NULL on error.
Free the returned object with g_object_unref().


Returns an output stream for overwriting the file in readwrite mode possibly creating a backup copy of the file first . If the file doesn ' t exist it will be created . For details about the behaviour see g_file_replace () which does the same thing but returns an output stream only . Note that in many non - local file cases read and write streams are not supported so make sure you really need to do read and write streaming rather than just opening for reading or writing . ( transfer full ) : a #GFileIOStream or %NULL on error . Free the returned object with g_object_unref () .
