You want something like this:

PedGeometry* min_geom = ped_geometry_new (dev, start, len);
PedGeometry* max_geom = ped_geometry_new (dev, start, dev->length - start);
constraint = ped_constraint_new_from_min_max (min_geom, max_geom);

All of the constraint constructors use ped_constraint_new()... the
others are just for convenience.

ped_constraint_intersect() is also useful... it allows you to require
several constraints to be satisfied simultaneously.  If you have
several conceptual requirements, it is a bit nicer to split them
up into several constraints, and then find the intersection of them all.

Cheers,
Andrew
