      Description

      Latest 3.1.

      Found by opening botan.cpp.

      MWE (or almost minimal, I hope it's enough ):

      #include <map>
      
      template<typename K, typename V>
      inline V search_map(const std::map<K, V>& mapping,
                          const K& key,
                          const V& null_result = V())
      {
          typename std::map<K, V>::const_iterator i = mapping.find(key);
          if(i == mapping.end())
              return null_result;
          return i->second;
      }
