bpm_read_tbt_mode_c

	status.i4.v = bpm_read_tbt_mode_c(house.ch.d, max_return.i4.v,
					  mode.i4a.r, num_returned.i4.r)

	This routine returns the BPM turn by turn data acquisition mode.

	house		ASCII house name (If a value of NULL is passed for
			this argument, all mode values for the present
			machine will be read.)
	max_return	maximum number of values to return
	mode		returned turn by turn data acquisition mode
			(BPM_TBT_TRIGGERED -> triggered mode,
			 BPM_TBT_CIRCULAR_BUFFER -> circular buffer mode)
	num_returned	returned number of status values returned

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOTYET		not supported for the currently selected
				machine
	CBS_INVARG		invalid house name
	otherwise		other ACNET error

	This function requires the following include files:

	ul_cbsaux/bpmuti.h, cnsparam_h, acnet_errors_h
