it sounds really great (except some minor things).

OCI_CNT_ENQUEUE is quite cryptic to me. I use OCI_CNT_AQMESSAGES in my
code as it sounds more descriptive to me (if course it's just a minor
stuff).

The proposed OCI_EventGetDequeue() - I assume it should use only
previously registered OCI_Dequeue by OCI_SubscriptionAddDequeue, right?

I fully agree that contain OCI_Dequeue in OCI_event is much better than
diplicated "queue name" and "consumer" etc. attributes.

So what about implementation, please? Should I do it or do you want to
do it yourself? (remember that you know OCI much better than me probably
;)).
In the case I should do it: can I access the latest code? Or should I
use the latest release?

thanks,
petr
