ITs under RTAI

    Hi all,

   I have some other questions about ITs under RTAI.
First of all if I set a handler to be called when
there is a interrupt on a irq line, is there a
global_cli() done by the IT dispatcher  when the
handler is called or did I have to do it on my own ?
 If not what will happen if an IT occurs while the
handler is running ? I ask that because I've assumed
that the principle of bottom halves is not used with
RTAI's ITs, so the handler might by long (in time).

  Is there any priority on the irq line with RTAI (for
example first the RT task then other whatever is the
irq line) ?

   Regards
   Jean-Denis ROUX
