[xmlblaster] about callback after connect

[Cyrille Giquello <cyrille at giquello.com>]

Hello,

is it possible to declare a callback to xmlBlaster after the connect() call.

I know to declare the callback in the connect Qos. I've read the 
interface.subscribe but no callback stuff possible in the Qos.

How can I do if need to declare a callback later ? Is it possible ?
Can we have multiple callback server ?

Hope that my question is clear enough ...

Thanks
cyrille.
