status.i4.v = bpm_get_tbt_crates_and_channels(crates.i4a.r,

	This routine retrieves BPM turn by turn detector crate and channel
	values for the machine last requested by a call to bpm_machine_c.
	A value of NULL can be passed for any of the returned arguments that
	are not needed.  The names for the crates can be retrieved using a
	call to bpm_crate_info_c.

	crates		array of turn by turn detector crate values
			(0 -> number of crates - 1)
	channels	array of turn by turn detector channel values
			(0 -> number of channels - 1)

	This function returns ACNET status values as follows:

	OK			success
	CBS_NOTYET		not yet supported for the active machine
	SQL_xxx			database access error

	This function requires the following include files:

	ul_cbsaux/bpmuti.h, acnet_errors_h
