bpm_get_offsets

	status.i4.v = bpm_get_offsets(horz_offsets.r4a.r [,vert_offsets.r4a.r])

	This routine retrieves BPM detector offsets for the machine last
	requested by a call to bpm_machine_c.  (Note:  For Main Injector
	only, if the "off" plane is currently selected for the BPMs, this
	routine will return the "off" plane offsets.)

	horz_offsets	array of horizontal detector offset values in mm
	[vert_offsets]	array of vertical detector offset values in mm
			(default is NULL)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOTYET		not yet supported for the active machine
	otherwise		Filesharing error

	This function requires the following include files:

	ul_cbsaux/bpmuti.h, acnet_errors_h

	bpm_get_sample_mode, bpm_get_locations, bpm_get_detector_status,
	bpm_get_crates_and_channels

	C/C++ usage:

	int		status;
	int		num_horizontal;
	int		num_vertical;
	float		*horz_offsets;
	float		*vert_offsets;

	bpm_query(&num_horizontal,&num_vertical);

	horz_offsets = (float *) malloc(num_horizontal*(sizeof(float)));
	vert_offsets = (float *) malloc(num_vertical*(sizeof(float)));

	status = bpm_get_offsets(horz_offsets,vert_offsets);
