status.i4.v = ftd_to_data_event_c(ftd.i2.v, data_event.s.r)

	This routine converts a Frequency Time Descriptor (FTD) to a
	data event value.

	ftd		Frequency Time Descriptor to convert
			(constants are in 'diolib')
	data_event	returned data event data (DATA_EVENT_DATA structure)

	This function returns ACNET status values as follows:

	OK			successful conversion
	CLIB_NOTYET		FTD value not supported

	This function requires the following include files:

	cbslib_h, diolib_h, cns_data_structs_h, acnet_errors_h

	C/C++ usage:

	short	ftd = FTD_1HZ;
	int	status;
