Enumeration Type Documentation

enum _LSEC_cnsState

Consignment state.

Enumerator:

LSEC_CNS_EMPTY	Ready to encode another event.
LSEC_CNS_FULL	An event has been encoded and is waiting to be consigned.

---

Function Documentation

LSEC_consignment* LSEC_consCreate	(	unsigned	cpuid,
		unsigned	srcid,
		unsigned	cap,
		LSEC_compaction *	cpc,
		LSEC_event *	evt,
		long long *	times
	)

Create a new consignment.

This routine allocates memory for a consigment structure and its associated data structures, and initialises it.

Parameters:

	srcid	ID of the data source
	cpuid	ID of the CPU the calibration is being run on
	cap	The capacity (in events) of the consignment
	cpc	Pointer to the compaction state information
	evt	Pointer to the event store
	times	Pointer to the processing times array.

Returns:

Pointer to an allocated, initialised consignment (NULL if there is an error allocating memory)

LSEC_ctx* LSEC_consCtxGet

(

LSEC_consignment *

cns

)

Get the address of the context structure.

Parameters:

cns

Pointer to the consignment structure

Returns:

The address of the context structure

void LSEC_consDelete

(

LSEC_consignment *

cns

)

Free the previously allocated consignment structure.

Parameters:

cns

Pointer to allocated, intialised consignment structure

unsigned LSEC_consEventCal	(	void *	parm,
		EBF_dir *	dir
	)

Process a compressed CAL event.

This routine starts the process by accumulating data for the CAL means calculation.

Parameters:

	parm	Pointer to the consignment structure
	dir	Pointer to the event directory

Return values:

LSEC_SUCCESS

Success (always)

unsigned LSEC_consEventImm	(	void *	parm,
		EBF_dir *	dir
	)

Process an event immediately.

This routine is used to pass an event immediately to the datagram framework. It is used in all cases except compressed CAL events.

Parameters:

	parm	Pointer to the consignment structure
	dir	Pointer to the event directory

Return values:

	LSEC_SUCCESS	Success
	LSEC_OVERSIZE	Event too large for a datagram

void LSEC_consPrepare	(	LSEC_consignment *	cns,
		unsigned	runid,
		unsigned	mode,
		LSEC_compLevel	comp
	)

Prepare for a new calibration run.

This routine sets the runid and start time for the first datagram of a new calibration, as well as several other mode-dependent parameters.

Parameters:

	cns	Pointer to allocated, intialised consignment structure
	runid	32-bit number identifying the calibration run
	mode	The calibration mode (ACD, CAL or TKR)
	comp	The compression level (normal, only, none)

unsigned LSEC_consProcess

(

LSEC_consignment *

cns

)

Process a consignment.

Parameters:

cns

Pointer to a consignment structure

Return values:

LSEC_SUCCESS

If all goes well

void LSEC_consReason	(	LSEC_consignment *	cns,
		int	reason
	)

Set the current datagram close reason.

Parameters:

	cns	Pointer to the consignment structure
	reason	The reason code to be set
