ststus.i4.v = dio_build_timer_reference_list_c(num_timers.i4.v,

	This routine builds a list to read clock events for a 177/377/379/477
	timer channel or a list of timer channels.  This routine also supports
	non-CAMAC timers which have the same ACNET device interface.

	num_timers	number of timers to read
	timer_devices	device index of timer or array of device indices
	errors		array of returned ACNET status values
	list_info	returned list information
			(structure of type DIO_TIMER_LIST_DATA)
			(to be used with dio_get_timer_reference_list and
	[data_event]	data event string for reading timer reference events
			(default is NULL which results in a one shot reading)

	This function returns status values as follows:

	OK			success
	DIO_MEMFAIL		dynamic memory allocation failure
	DIO_INVDEV		not a timer device
	DIO_NO_SUCH		invalid timer database entries
	negative value		ACNET format error indicating overall failure
	positive value		number of timers in error

	This function requires the following include files:

	diolib_h, tclk_events_h, acnet_errors_h
