Function Documentation

unsigned int CDF_dgn_compress (  CDF_dgn *  cdf, unsigned int *  buf, unsigned int  pos, const EBF_dir *  dir )

Compresses the DGN contributions. Returns: The updated write bit position Parameters: cdf  The DGN compression data formatting handle buf  The output buffer pos  The position of the next bit to fill dir  The directory describing the event to be formatted

int CDF_dgn_construct (  CDF_dgn *  cdf, int  level, const CDF_dgnCfg *  cfg, const LSEW_dgmFw *  dgmFw, void **  mem )

Constructs the CDF_dgn compression context. Return values: Status  Parameters: cdf  The CDF_dgn 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_dgn, else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_dgn_sizeof (  int  level, const CDF_dgnCfg *  cfg )

Returns the size, in bytes of the DGN compression structure needed to support the specified level. Parameters: level  The maximum compression level to support cfg  Target specific configuration

int CDF_dgnCfg_construct (  CDF_dgnCfg *  cfg, int  level, void **  mem )

Constructs the CDF_dgnCfg 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_dgnCfg else this routine will believe that the only the variable allocation of cdf needs to be allocated.

int CDF_dgnCfg_sizeof (  int  level  )

Returns the size, in bytes of the DGN compression configuration needed to support the specified level. Parameters: level  The maximum compression level to support
