bpm_beam_cycle_info

	status.i4.v = bpm_beam_cycle_info(beam_event.i4.r [,cycle_number.i4.r]
					  [,turn_number.i4.r])

	This routine returns the cycle information for the last successfully
	retrieved BPM data for the currently selected machine.	See
	bpm_machine_c.

	beam_event		returned TCLK event triggering the beam cycle
				(constants are in tclk_events)
	[cycle_number]		returned number of the beam cycle in the
				super cycle  (This is the state number
				for Main Injector.)
	[turn_number]		starting turn number on which the beam was
				sampled (BPM_BOOSTER only)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOTYET		not supported for the currently selected
				machine

	This function requires the following include files:

	ul_cbsaux/bpmuti.h, acnet_errors_h, tclk_events_h

	Related functions:

	bpm_machine_c, bpm_get_data_c, blm_get_data_c

	C/C++ usage:

	int		status;
	int		beam_event;
	int		cycle_number;
	int		turn_number;

	status = bpm_beam_cycle_info(&beam_event,&cycle_number,&turn_number);
