status.i4.v = find_time_slot_list_c(main_devices.i1a.r, time.r4.v, 
					    slot_numbers.i2a.r, errors.i2a.r,
					    num_devices.i4.v, same_table.i4.v)

	This function returns the time slot in a time table that immediately
	precedes the time passed in.  If the time exactly matches a value
	in the time table, that slot number is returned.  This function 
	is currently valid only for 46x devices.

	main_devices	names of base (no suffix) 465 devices
       time		time in seconds
	table_numbers	array of time table numbers to search
			(each value should be between 1 and C465_NUM_TABLES)
	slot_numbers	returned time table slot number or array of slot numbers
			(CBS_NO_SUCH -> time is greater than total time
					in table,
			 0 -> value is less than first slot of table,
			 >0 -> preceding slot number)
	errors		returned ACNET status value or array of status values
	num_devices	number of devices
	same_table	flag whether or not all entries in "table_numbers" are
			the same
			(TRUE -> use first value in "table_numbers"
				 for every device requested,
			 FALSE -> each entry in "table_numbers" will
				  be treated as unique)

       This function returns status values as follows:

	CBS_MEMFAIL		dynamic memory allocation failure
	CBS_INVARG		invalid root name (no blanks) or table number
	CBS_INVSIZ		invalid family size (database entry error)
	CBS_INVTYP		device is not a waveform generator
	CBS_NO_SUCH		family device not found
	negative value		other ACNET error
	positive value		number of devices not having a slot
				corresponding to the requested time

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, acnet_errors_h
