Thanks for the reply Richard.
The interrupt is not a GPIO pin. I have read something about UIO (userspace I/O).
Also, I want the operation to be asynchronous. Any pointer to such mechanism will be very helpful.
Regards,
Amit.

Is the interrupt pin a gpio?
If so, you can access it from userspace and identify interrupts using poll().
