llrf_get_curve_devices_c

	status.i4.v = llrf_get_curve_devices_c(device_index.i4.v,
					       times_device.i4.r,
					       values_device.i4.r,
					       control_device.i4.r)

	This routine returns the devices related to a LLRF curve.

	device_index	device index which references the requested curve
	times_device	returned device index to access the time values
	values_device	returned device index to access the curve values
	control_device	returned device index to control access to the curve

	This function returns ACNET status values as follows:

	OK			success
	DIO_NOT_SUPPORTED	unsupported device (not a LLRF curve device)
	negative value		other ACNET error

	This function requires the following include files:

	ul_cbsaux_h:auxlib_device_h, acnet_errors_h
