Function Documentation

QDF_esbCtx * QDF_tkrCtxConstruct	(	QDF_tkrCtx *	ctx,
		unsigned int	level,
		QDF_tkrCache *	cache,
		const QSE_ctx *	qse
	)

Constructs (initializes) the specified TKR 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.
	cache	The TKR caches
	qse	Pointer to the public/generic QSE context parameter

int QDF_tkrCtxSizeof	(	unsigned int	level,
		void *	prm
	)

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

Returns:

The size, in bytes, of the TKR decoding context

Parameters:

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

int QDF_tkrCtxUpdate	(	QDF_tkrCtx *	ctx,
		QFR_fileCtx *	qfr,
		const CDF_tkrBdy *	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_esbCtx * QDF_tkrEvtConstruct	(	QDF_tkrEvt *	evt,
		unsigned int	level,
		void *	prm,
		QDF_exc *	exc,
		QDF_esbEvt *	esb,
		QDF_gemEvt *	gem,
		QDF_errEvt *	err
	)

Constructs (initializes) the specified TKR event structure.

Returns:

Pointer to the context structure to construct

Parameters:

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

int QDF_tkrEvtSizeof	(	unsigned int	level,
		void *	prm
	)

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

Returns:

The size, in bytes, of the TKR event

Parameters:

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

static int splits_construct	(	QDF_tkrSplits *	splits,
		const TCC_DB_schema *	schema
	)			[static]

Constructs the Tracker Split Point database.

Returns:

Status

Parameters:

	splits	The Tracker Split Point database to fill
	schema	The Tracker Configuration database

If a TCC_DB CDM database is found, then the values are taken from there, otherwise, they are just defaulted to the mid-point (12/12)

static __inline void splits_default_construct

(

QDF_tkrSplits *

splits

)

[static]

Initializes the track split points to their default values.

Parameters:

splits

The TKR split point limits structure to initialize

static unsigned int tkrCtxCfgConstruct	(	QDF_tkrCtx *	ctx,
		const TCC_DB_schema *	schema,
		const char *	name
	)			[static]

Constructs the TKR configuration from the specified database.

Return values:

	!=	0 The checksum.
	==	0 Failure (0 is not a valid checksum

Parameters:

	ctx	The TKR context structure
	schema	The TKR configuration database schema
	name	The TKR configuration file name,
