[ECOS] about ramfs.cxx

Hi,now i am reading ramfs.cxx.

In function findbuffer_indirect1 some lines as followed:

      int bi = pos / RAMFS_INDIRECT1_BLOCK_EXTENT;
      int bpos = pos % RAMFS_INDIRECT1_BLOCK_EXTENT;
      int err;
      cyg_uint8 *b;
      size_t sz;

 

    // Use findbuffer_direct() to index and allocate
    // the first level indirect block.
   
    err = findbuffer_direct( bi,   

                                    (ramfs_block **)blocks,
                                    nblocks,
                                    &b,
                                    &sz,
                                    alloc);

i don't know why findbuffer_direct's first parameter is bi but not bi*CYGNUM_RAMFS_BLOCK_SIZE.

     Thanks.
