I'm writing an FFI wrapper around OSQP, which has structs such as these <https://github.com/osqp/osqp/blob/master/include/types.h#L21>, in which multiple pointers are set to point to memory with a length specified in another field.

What's the difference between null? and empty?
<bremner>
I think just history. maybe null? is original in scheme?
<bremner>

ah yeah. I checked chezscheme. No empty? there.
