status.i4.v = dio_timer_max_events_c(device_indices.i4a.r,
					     errors.i2a.r, max_events.i4a.r

	This routine determines the maximum number of reference clock events
	for a timer channel.

	device_indices	device index of timer or array of device indices
	errors		array of returned ACNET status values
	max_events	returned array of the maximum number of reference
			clock events
	[num_timers]	number of timers to check
			(default is 1)

	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, acnet_errors_h
