	This routine allows a process to send an alarm message with
	an accompanying text message.

	device_index	device index to submit alarm for
	alarm_type	type of alarm
			(DIO_ANALOG -> analog alarm,
			 DIO_DIGITAL -> digital alarm)
	event_type	type of alarm event
			(ALARM_EXCEPTION -> exception type alarm (bad/good),
			 ALARM_EVENT -> event type alarm)
	text		text string to be included in the alarm report
			as a parameter (included into the display message
			by the "!TX" formatting directive) (a maximum
			of ALARM_TEXT_LEN characters can be used)
	text_length	length of alarm text string (If this argument
			has a value of zero, the routine will determine
			the length of the string.)
	reading		"reading" value which is primarily used to
			provide numeric information for alarm text
			formatting directives
	good_bad	value to set the GOOD/BAD bit in the alarm status
			(ALARM_GOOD -> alarm is going good,
			 ALARM_BAD -> alarm is going bad)
	high_low	setting for HI/LO bits in the alarm status
			(ALARM_LOW -> low alarm,
			 ALARM_NO_LOHI -> alarm is neither low nor high,
			 ALARM_HIGH -> high alarm)

	This function returns status values as follows:

	OK			success
	CLIB_INVARG		invalid parameter passed for alarm type,
				event type, good/bad status, high/low status
	DIO_NOATT		requested alarm property does not exist
	DIO_INVDEV		requested device is not a software alarm device
	DIO_xxx			error retrieving alarm node
	ACNET_xxx		ACNET communication error

	This function requires the following include files:

	clib_h, acnet_errors_h
