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 gio.types.FileCreateFlags.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 gio.types.IOErrorEnum.Cancelled will be
returned.
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.

If a file or directory with this name already exists, the gio.types.IOErrorEnum.Exists error will be returned. Some file systems don't allow all file names, and may return an gio.types.IOErrorEnum.InvalidFilename error, and if the name is too long, gio.types.IOErrorEnum.FilenameTooLong will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
