Detailed Description

Macro Definition Documentation

#define UIP_DS6_DEFRT_NBS   0

Configuration.

For all tables (Neighbor cache, Prefix List, Routing Table, Default Router List, Unicast address list, multicast address list, anycast address list), we define:

• the number of elements requested by the user in contiki configuration (name suffixed by _NBU)
• the number of elements assigned by the system (name suffixed by _NBS)
• the total number of elements is the sum (name suffixed by _NB)
