Using GIOChannel synchronously and asynchronously

[silverburgh <silverburgh meryl gmail com>]

Hi,

I am trying to use GIOChannel with a socket on Linux.
I would like to know if I need to set the socket to 'non blocking'
mode before I setup the GIOChannel?
And If I can mix my GIOChannel read/write operation synchronously and
asynchronously? If yes, how can I do that?

Thank you.
