Creates a new file and returns a stream for reading and
writing to it. The file must not already exist.
By default files created are generally readable by everyone,
but if you pass #G_FILE_CREATE_PRIVATE in @flags the file
will be made readable only to the current user, to the level
that is supported on the target filesystem.
If @cancellable is not %NULL, then the operation can be cancelled
by triggering the cancellable object from another thread. If the
operation was cancelled, the error %G_IO_ERROR_CANCELLED will be
returned.
If a file or directory with this name already exists, the
%G_IO_ERROR_EXISTS error will be returned. Some file systems don't
allow all file names, and may return an %G_IO_ERROR_INVALID_FILENAME
error, and if the name is too long, %G_IO_ERROR_FILENAME_TOO_LONG
will be returned. Other errors are possible too, and depend on what
kind of filesystem the file is on.
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.
