If you are calling Comedi from kernel space, like from a real-time
module, yes.  You should look at the real-time examples.

If you are using Comedi from user space, yes, using SIGIO.  But
I'm almost 100% certain that you don't really want to do that,
unless you really know what you're doing.  So don't.  Use select()
instead.
