What you are talking about is a device driver. It is not possible to
get to the interrupt vectors from a userland application (at least it
should not be allowed). I would suggest that you look into writing a
device driver for the application to use. A fine reference book on how
to write device drivers is from O'Reilly ( "Linux
Device Drivers" by Alessandro Rubini, the ISBN is: 1-56592-292-1.
