FYI : Look at you EPICS base  at src/libCom/osi/devLib.c.

You should use devConnectInterrupt(intVME, SCAN_INT_NUMBER, pFunction, (void*)
&a)
and  devEnableInterruptLevel(intVME, SCAN_INT_LEVEL).

The example file could be found at
http://www.nsls.bnl.gov/facility/expsys/software/EPICS/
under synAppsRTEMS.  The filename is vmeApp/src/drvIK320.c.
