Function Documentation

QDF_temCtx* QDF_temCtxConstruct	(	QDF_temCtx *	ctx,
		unsigned int	level,
		QDF_temCache *	cache,
		const QSE_ctx *	qse,
		void *	ptr
	)

Constructs (initializes) the specified TEM 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 TEM caches
	qse	Pointer to the public/generic QSE context parameter
	ptr	Pointer to the memory pool to carve the various pieces from. It assumed that the user call QDF_temCtxSizeof to determine the necessary size.

int QDF_temCtxSizeof	(	unsigned int	level,
		void *	prm
	)

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

Returns:

The size, in bytes, of the TEM decoding context

Parameters:

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

QDF_temEvt* QDF_temEvtConstruct	(	QDF_temEvt *	evt,
		unsigned int	level,
		void *	prm,
		void *	ptr,
		QDF_exc *	exc,
		QDF_esbEvt *	esb,
		QDF_gemEvt *	gem
	)

Constructs (initializes) the specified TEM event structure.

Returns:

Pointer to the context structure to construct

Parameters:

	evt	The TEM event structure to construct.
	level	The maximum level of compression that will be supported.
	prm	Additional configuation parameter, unused as of now
	ptr	The available memory
	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

int QDF_temEvtSizeof	(	unsigned int	level,
		void *	prm
	)

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

Returns:

The size, in bytes, of the TEM event

Parameters:

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