interrupt numbers

Is there a way to get all the interrupt numbers in a program from the OS?
This would be under RTP 6.1A. I’m looking for the Ethernet interrupt
number, and I know I can find it from nicinfo, but I’m thinking there has to
be a way to ask for this from the kernel, possibly via the syspage. I know
you can get the timer interrupt via: SYSPAGE_ENTRY( qtime ) ->intr but
browsing the header files does not reveal where I might find other
interrupts of this nature like the serial or Ethernet interrupt. Any
assistance would be greatly appreciated.
