setCloseOnUnref
Whether to close the channel on the final unref of the #GIOChannel data structure. The default value of this is true for channels created by g_io_channel_new_file (), and false for all other channels.
Setting this flag to true for a channel you have already closed can cause problems when the final reference to the #GIOChannel is dropped.
Parameters
