Function Documentation

unsigned int CDF_err_compress (  CDF_err *  cdf, unsigned int *  buf, unsigned int  pos, const EBF_dir *  dir )

Compresses the ERR contributions. Returns: The updated write bit position Parameters: cdf  The ERR 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_err_construct (  CDF_err *  cdf, int  level, const CDF_errCfg *  cfg, const LSEW_dgmFw *  dgmFw, void **  mem )

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

int CDF_err_sizeof (  int  level, const CDF_errCfg *  cfg )

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

int CDF_errCfg_construct (  CDF_errCfg *  cfg, int  level, void **  mem )

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

int CDF_errCfg_sizeof (  int  level  )

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