c465_find_level_c

	status.i4.v = c465_find_level_c(main_device.i1a.r, event.i4.v)

	This routine returns the interrupt level in a C465/6/7/8/0 module
	containing the selected TCLK event.

	main_device	name of base (no suffix) 465 device
	event		TCLK event (constants are in 'tclk_events')
			(do not specify EVENT_NULL or EVENT_NOOP)

	This function returns status values as follows:

	CBS_INVARG		invalid root name (no blanks) or event
	CBS_INVSIZ		invalid family size (database entry error)
	CBS_INVTYP		device is not a C465 module
	CBS_NO_SUCH		clock event or family device not found
	negative value		other ACNET error
	otherwise		interrupt level containing TCLK event

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, tclk_events_h, acnet_errors_h
