size0	size of column 0, in byte.
size1	size of column 1, in byte.
size2	size of column 2, in byte.
c0vec_ptr	buffer pointer to column 0.
c1vec_ptr	buffer pointer to column 1.
c2vec_ptr	buffer pointer to column 2.
nrow	number of row to scan.
c0_strm	array of column 0 stream.
c1_strm	array of column 1 stream.
c2_strm	array of column 2 stream.
e_row_strm	array of output end flag stream.
