/**
 * Description
 * The GIOChannel data type aims to provide a portable method for
 * using file descriptors, pipes, and sockets, and integrating them
 * into the main event
 * loop. Currently full support is available on UNIX platforms,
 * support for Windows is only partially complete.
 * To create a new GIOChannel on UNIX systems use
 * g_io_channel_unix_new(). This works for plain file descriptors,
 * pipes and sockets. Alternatively, a channel can be created for a
 * file in a system independent manner using g_io_channel_new_file().
 * Once a GIOChannel has been created, it can be used in a generic
 * manner with the functions g_io_channel_read_chars(),
 * g_io_channel_write_chars(), g_io_channel_seek_position(), and
 * g_io_channel_shutdown().
 * To add a GIOChannel to the main event loop use
 * g_io_add_watch() or g_io_add_watch_full(). Here you specify which
 * events you are interested in on the GIOChannel, and provide a
 * function to be called whenever these events occur.
 * GIOChannel instances are created with an initial reference count of
 * 1. g_io_channel_ref() and g_io_channel_unref() can be used to
 * increment or decrement the reference count respectively. When the
 * reference count falls to 0, the GIOChannel is freed. (Though it
 * isn't closed automatically, unless it was created using
 * g_io_channel_new_from_file().) Using g_io_add_watch() or
 * g_io_add_watch_full() increments a channel's reference count.
 * The new functions g_io_channel_read_chars(),
 * g_io_channel_read_line(), g_io_channel_read_line_string(),
 * g_io_channel_read_to_end(), g_io_channel_write_chars(),
 * g_io_channel_seek_position(), and g_io_channel_flush() should not be
 * mixed with the deprecated functions g_io_channel_read(),
 * g_io_channel_write(), and g_io_channel_seek() on the same channel.
