Then would depend on how we would define how the grouping is handled and how the GetIndices would be used. Some possibilities

1) ISGetIndices(is,int group_number, &indices) gives the indices for a group or

So by convention, group 0 is "offset" and group 1 is "size"? Do we need an arbitrary number of groups? (Making the object more general makes it harder to reason about what it does and harder to write non-implementation code that manipulates these objects.)

2) ISGetIndices(is,&indices) simply returns all the indices for all the groups

That would need to be packed somehow.
