FileT.replaceReadwrite

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.
