Jan> addrmap.[ch] for API or the `find' command for CLI.

VEC also has a binary search built-in, under a funny name:

/* Find the first index in the vector not less than the object.
   unsigned VEC_T_lower_bound (VEC(T) *v, const T val,
                               int (*lessthan) (const T, const T)); // Integer
   unsigned VEC_T_lower_bound (VEC(T) *v, const T val,
                               int (*lessthan) (const T, const T)); // Pointer
   unsigned VEC_T_lower_bound (VEC(T) *v, const T *val,
                               int (*lessthan) (const T*, const T*)); // Object

   Find the first position in which VAL could be inserted without
   changing the ordering of V.  LESSTHAN is a function that returns
   true if the first argument is strictly less than the second.  */

#define VEC_lower_bound(T,V,O,LT)    \
   ...
