* UBYTE operationStatusId 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 operation interrupts.
*
* OUTPUT: PLC540V_STATUS_TYPE *status will contain the final status
* of requesting this function. This status could be and EPC
* or PLC-5/40V value.
*
* RETURNS: Nothing.
*
* EXAMPLE:
* ULONG vmeCmdBlkAddr = 0x90000;
* UWORD baseAddress = 0xFC00;
* VME_INTERRUPT_LEVEL_TYPE cmdIntLevel = kVME_NO_INT_LEVEL;
* UBYTE cmdStatusId = 0;
* VME_INTERRUPT_LEVEL_TYPE operationIntLevel=kVME_INT_LEVEL_3;
* UBYTE operationStatusId = 234;
* PLC540V_STATUS_TYPE status;
* plc540v_halt_handle_interrupts(
* vmeCmdBlkAddr,
* baseAddress,
* cmdIntLevel,
* cmdStatusId,
* operationIntLevel,
* operationStatusId,
* &status);

* PURPOSE: This function configures the PLC-5/40V to 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.
