Retrieve the prior record for the specified cursor.

For local tables only, if pRecNum is not null, the corresponding record number is returned. This example uses the following input:
         fDbiGetPriorRecord(hCursor, pRecBuf, &RecNum);

DBIResult fDbiGetPriorRecord(hDBICur hTmpCur, pBYTE pTmpRecBuf, pUINT32 pRecNum)

{

  DBIResult      rslt;

  CURProps       CurProps;

  RECProps       RecProps;

  rslt = Chk(DbiGetPriorRecord(hTmpCur, dbiNOLOCK, pTmpRecBuf, &RecProps));

  if (rslt != DBIERR_NONE)

     return rslt;

  if (pRecNum != NULL)

  {

     rslt = Chk(DbiGetCursorProps(hTmpCur, &CurProps));

     if (rslt != DBIERR_NONE)

        return rslt;

     if (strcmp(CurProps.szTableType,  szPARADOX) == 0)

        *pRecNum = RecProps.iSeqNum;

     else

     {

        if (strcmp(CurProps.szTableType,  szDBASE) ==0)

           *pRecNum = RecProps.iPhyRecNum;

        else

           *pRecNum =0;

     }

  }

  return rslt;

}
