unsigned LSEC_checkCompaction (  LSEC_compaction *  cpc  )

Check the substructures for errors. Parameters: cpc  Pointer to a compaction object Returns: The last error from the first substrcture to be found in error or LSEC_SUCCESS if there are no errors

void LSEC_clearCompaction (  LSEC_compaction *  cpc  )

Clear away any context from a previous cycle. Parameters: cpc  Pointer to a compaction object

unsigned int* LSEC_consignEvt (  LSEC_compaction *  cpc, unsigned int *  buf )
