kws_raw_read block param value less than 10 will cause func alway return -1

because

     int block_n = block / 10;  //block_n will be 0
      ...
     kws->x++;  //x will be at least 1
      ...
     if (kws->x >= 10000 || (block && kws->x >= block_n)) {   //so this will alway true and return -1

do you have a suggested fix? or just pass in a value of block > 10 ?
