Function Documentation

static unsigned int acdCtxPedsConstruct	(	QDF_acdCtx *	ctx,
		const ACD_DB_schema_pedestals *	peds,
		const char *	name
	)			[static]

Constructs the pedestals from the ACD database of pedestals.

Returns:

The checksum. This is a Fletcher style checksum. On failure, 0 is returned

Parameters:

	ctx	The ACD context structure
	peds	The ACD pedestals database schema
	name	The ACD CDM database file name,

QDF_acdCtx * QDF_acdCtxConstruct	(	QDF_acdCtx *	ctx,
		unsigned int	level,
		void *	prm,
		const QSE_ctx *	qse
	)

Constructs (initializes) the specified ACD decoding context structure.

Returns:

Pointer to the context structure to construct

Parameters:

	ctx	The context structure to construct.
	level	The maximum level of compression that will be supported.
	prm	Additional configuation parameter, unused as of now
	qse	The generic datagram context

int QDF_acdCtxSizeof	(	unsigned int	level,
		void *	prm
	)

Returns the size, in bytes of the ACD decoding context needed to support the specified compression level.

Returns:

The size, in bytes, of the ACD decoding context

Parameters:

	level	The maximum level of compression that needs to be supported
	prm	Additional configuation parameter, unused as of now

int QDF_acdCtxUpdate	(	QDF_acdCtx *	ctx,
		QFR_fileCtx *	qfr,
		const CDF_acdBdy *	bdy
	)

Updates the ACD context from the datagram contribution.

Return values:

	0,Success
	0x80000001,Pedestal	file error, not found
	0x80000002,Pedestal	file error, checksum does not match

Parameters:

	ctx	The context to update
	qfr	The file translation context
	bdy	The update information

QDF_acdEvt * QDF_acdEvtConstruct	(	QDF_acdEvt *	evt,
		unsigned int	level,
		void *	prm,
		QDF_exc *	exc,
		QDF_esbEvt *	esb,
		QDF_gemEvt *	gem
	)

Constructs (initializes) the specified ACD event structure.

Returns:

Pointer to the context structure to construct

Parameters:

	evt	The ACD event structure to construct.
	level	The maximum level of compression that will be supported.
	prm	Additional configuation parameter, unused as of now
	exc	The exception handling context.
	esb	Pointer to the Event Summary Data for this event
	gem	Pointer to the GEM data for this event

int QDF_acdEvtSizeof	(	unsigned int	level,
		void *	prm
	)

Returns the size, in bytes of QDF_acd event needed to support the specified compression level.

Returns:

The size, in bytes, of the ACD event

Parameters:

	level	The maximum level of compression that needs to be supported
	prm	Additional configuation parameter, unused as of now
