Function Documentation

void CDF_tkr_begin	(	CDF_tkr *	cdf,
		CDF_tkrBdy *	bdy
	)

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

Parameters:

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

int CDF_tkr_check	(	CDF_tkr *	cdf,
		const EDR_tkr *	tkr
	)

Checks that the splits points of all struck layers are consistent with the configuration.

Return values:

	==0	if successful
	<	0 serious structural problems
	>	0 a bit mask (low 16 bits) of the towers that can not be compressed.

Parameters:

	cdf	The CDF_cal compress context structure
	tkr	The unpacked tracker record

int CDF_tkr_construct	(	CDF_tkr *	cdf,
		int	level,
		const CDF_tkrCfg *	cfg,
		const LSEW_dgmFw *	dgmFw,
		void **	mem
	)

Constructs the CDF_cal compression context.

Return values:

Status

Parameters:

	cdf	The CDF_cal 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_tkr, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_tkr_sizeof	(	int	level,
		const CDF_tkrCfg *	cfg
	)

Returns the size, in bytes of the CAL compression structure needed to support the specified level.

Parameters:

	level	The maximum compression level to support
	cfg	Target specific configuration

int CDF_tkrCfg_construct	(	CDF_tkrCfg *	cfg,
		int	level,
		void **	mem
	)

Constructs the CDF_tkr 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_tkrCfg, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_tkrCfg_sizeof

(

int

level

)

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

Parameters:

level

The maximum compression level to support
