*
* PURPOSE: This function configures the PLC-5/40V to not recognize the
* specified VME interrupts.
*
* INPUT: ULONG vmeCmdBlkAddr contains the VME address where the
* command block will be copied to so the PLC-5/40V can
* access its information.
*
* UWORD baseAddress contains the base address of the
* PLC-5/40V.
*
* VME_INTERRUPT_LEVEL_TYPE cmdIntLevel contains the VME bus
* interrupt to be generated by the PLC-5/40V AFTER storing
* its response in the response word of the command block AFTER
* COMMAND completion. If kVME_NO_INT_LEVEL is specified, then
* no VME bus interrupts will be generated.
*
* UBYTE cmdStatusId contains a unique value which will be used
* by the interrupted host processor to run a specific
* interrupt service routine. This variable must be set to
* zero if you are NOT using any command interrupts.
*
* VME_INTERRUPT_LEVEL_TYPE operationIntLevel contains the VME
* bus interrupt to be generated by the PLC-5/40V AFTER each
* copy OPERATION. If kVME_NO_INT_LEVEL is specified, then
* ALL VME interrupts will be disabled.
