How do I define a thin binding to getdent(2) syscall in Spark?
This syscall returns a unknown number of entries into a separate area.
In Ada95 I'd return a array slice. In Spark, this is not possible.

What is the canonical way to deal with this?

Introduce state and return the number (and the state) first, followed by a
procedure call returning all the entries at once?
