If you want the data interleaved by cell, you'll need to read a row
from each map then interleave the values yourself, e.g.
DCELL *row_buf = G_malloc(ncols * nbands * sizeof(DCELL));
for (row = 0; row < nrows; row++) {
for (band = 0; band < nbands; band++) {
G_get_d_raster_row(fds[band], bufs[band], row);
for (col = 0; col < ncols; col++)
row_buf[col * nbands + band] = bufs[band][col];
...
