	This routine returns the analog alarm limits for a device.  If the
	parameter "limit_type" is used, the type of limit is returned.

	device_index	device index of interest
	minimum		returned alarm minimum
	maximum		returned alarm maximum
	[limit_type]	returned type of limit
			(DIO_NOMTOL -> nominal and tolerance,
			 DIO_NOMPER -> nominal and percent tolerance,
			 DIO_MINMAX -> minimum and maximum)
	[ftd]		frequency time descriptor
			(FTD_ONESHOT -> one shot (default),
			 FTD_DEFAULT -> use database default FTD,
			 FTD_1HZ -> 1 Hz request,
			 FTD_EVENT_MASK OR'ed with TCLK event value -> read
			 on TCLK event (event constants are in tclk_events)
			 (can use the macro BUILD_EVENT_FTD(event) or
			  BUILD_EVENT_PLUS_DELAY_FTD(event,delay) in 'macro'))
	[units_text]	returned units text (LEN_DEV_UNITS characters)
	[start_block]	starting block to return (starts at 0)
			(default is 0) (maximum is DIO_MAX_ALARM_BLOCKS - 1)
	[max_blocks]	maximum number of blocks to return per device
			(default is 1) (maximum is DIO_MAX_ALARM_BLOCKS)
	[num_blocks]	returned number of blocks returned (default is NULL)
	[limit_status]	returned array of individual limit status values
			(DIO_ALARM_LIMITS_OK -> both alarm limits were
						successfully returned,
			 DIO_ALARM_MINIMUM_OK -> only the alarm minimum
						 was successfully returned,
			 DIO_ALARM_MAXIMUM_OK -> only the alarm maximum
						 was successfully returned,
			 DIO_ALARM_LIMITS_BAD -> neither alarm limit was
						 successfully returned)
			(default is NULL)

	This function returns ACNET status values as follows:

	OK			success
