in s7, and use memcpy to copy the data from the C int64_t<br>
or double array (or actually share the data: see<br>
s7_float_vector_elements and s7_int_vector_elements).<br>
If the inner vectors are all the same size, you<br>
can grab all of them in one operation by using<br>
s7 multidimensional vectors. Otherwise, I think<br>
you'll need to use s7_integer, s7_real, and maybe<br>
the make-* cases -- kinda slow, perhaps --<br>
I'm probably forgetting something obvious.<br>
