dio_is_ramping_c

	status.i4.v = dio_is_ramping_c(device_index.i4.v, ramping_status.i4.r,
				       ramping_text.i1a.r, ftd.i2.v)

	This routine retrieves device ramp/DC status.

	device_index	device index
	ramping_status	returned ramp/DC status
			(TRUE -> device is ramping,
			 FALSE -> device is DC,
			 DIO_NOATT -> ramp/DC attribute is not defined)
	ramping_text	returned 4 characters of status text ("RAMP" or "DC  ")
			(A value of NULL can be passed for this argument,
			 if this string is not needed.)
	ftd		frequency/time that data is collected
			(FTD_ONESHOT -> one shot,
			 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'))

	This function returns ACNET status values as follows:

	OK			success
	DIO_BADARG		invalid number of arguments passed
	negative value		ACNET format error

	This function requires the following include files:
