status.i4.v = wg_find_table_numbers_c(main_device.i1a.r, event.i4.v,
					      time_table.i2.r, gi_table.i2.r,

	This routine returns the time, G(I), and H(I) table numbers
	in a C465/6/7/8/0, C453, C473, V473, or C475 module corresponding
	to the selected TCLK event.  If any of the table numbers are not
	needed, a value of NULL can be passed for the corresponding

	main_device	name of base (no suffix) device
	event		TCLK event (constants are in 'tclk_events')
			(do not specify EVENT_NULL or EVENT_NOOP)
	time_table	returned time table number (0-15)
			(0 -> null time table,
			 otherwise -> time table number)
	gi_table	returned G(I) table number (0-15)
			(0 -> null G(I) table,
			 otherwise -> G(I) table number)
	hi_table	returned H(I) table number (0-15)
			(0 -> null H(I) table,
			 otherwise -> H(I) table number)

	This function returns ACNET 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 C465/6/7/8/0, C453, C473,
				V473, or C475 module
	CBS_NO_SUCH		clock event or family device not found
	negative value		other ACNET error

	This function requires the following include files:

	cnsparam_h, ul_cbsaux_h:auxlib_device_h, tclk_events_h, acnet_errors_h
