How to use GIOChannel to write binary data

[silverburgh <silverburgh meryl gmail com>]

Hi,

In the gio channel,
http://library.gnome.org/devel/glib/stable/glib-IO-Channels.html#g-io-channel-write,
there are these api to write characters
g_io_channel_write_chars
g_io_channel_write_unichar

But why there is no api to write binary data? How can i use GIO
channel to write non-character data?

Thank you.
