Function Documentation

void CDF_acd_begin	(	CDF_acd *	cdf,
		CDF_acdBdy *	bdy
	)

Fills int the ACD portion of the datagram contribution used in when decoding an ACD event.

Parameters:

	cdf	The CDF_acd compress context structure
	bdy	The CDF_acdBdy structure to fill

int CDF_acd_construct	(	CDF_acd *	cdf,
		int	level,
		const CDF_acdCfg *	cfg,
		const LSEW_dgmFw *	dgmFw,
		void **	mem
	)

Constructs the CDF_acd compression context.

Return values:

Status

Parameters:

	cdf	The CDF_acd compress context structure to fill
	level	The maximum compression level that needs to be supported
	cfg	Target specific configuration parameter
	dgmFw	The datagram framework handle
	mem	Pointer to free memory pointer, return as the the updated pointer. If cdf is equal to the current contents of mem, then mem will be advanced by the size of CDF_acd, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_acd_sizeof	(	int	level,
		const CDF_acdCfg *	cfg
	)

Returns the size, in bytes of the GEM/ACD compression structure needed to support the specified level.

Parameters:

	level	The maximum compression level to support
	cfg	Target specific configuration

int CDF_acdCfg_construct	(	CDF_acdCfg *	cfg,
		int	level,
		void **	mem
	)

Constructs the CDF_acdCfg compression configuration.

Return values:

Status

Parameters:

	cfg	Target specific configuration
	level	The maximum compression level that needs to be supported
	mem	Pointer to free memory pointer, return as the the updated pointer. If cfg is equal to the current contents of mem, then mem will be advanced by the size of CDF_acdCfg, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_acdCfg_sizeof

(

int

level

)

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

Parameters:

level

The maximum compression level to support
