dio_get_raw_device_knob_info_c

	status.i4.v = dio_get_raw_device_knob_info_c(num_devices.i4.v,
						     device_indices.i4a.r,
						     errors.i2a.r,
						     knob_info.sa.r)

	This routine retrieves information for knobbing raw device values.

	num_devices	number of devices
	device_indices	device index or array of device indices
	errors		returned ACNET status value or array of status values
	knob_info	returned raw device value knobbing information
			(structures of type KNOB_RAW_DEVICE_INFO)
			(These structures can be passed to future calls to
			 'knob_raw_device_value_c'.)

	This function returns ACNET status values as follows:

	OK			success
	DIO_BADARG		invalid property index or number of devices
				passed
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error
	positive value		number of devices in error

	This function requires the following include files:

	diolib_h, cns_data_structs_h, acnet_errors_h

	Related functions:

	knob_raw_device_value_c, dio_scaling, error_in_list(_c)

	C/C++ usage:

	short	errors[NUM_DEVICES];
	int	status;
	int	num_devices = NUM_DEVICES;
	static const int	device_indices[NUM_DEVICES] = {202014, 140013};
	KNOB_RAW_DEVICE_INFO	knob_info[NUM_DEVICES];

	status = dio_get_raw_device_knob_info_c(num_devices,device_indices,
						errors,knob_info);
