``` /** Whether every node in the circ must have adequate uptime. */ int need_uptime; /** Whether every node in the circ must have adequate capacity. */ int need_capacity; /** Whether the last hop was picked with exiting in mind. */ int is_internal; /** Did we pick this as a one-hop tunnel (not safe for other conns)? * These are for encrypted connections that exit to this router, not * for arbitrary exits from the circuit. */ int onehop_tunnel; ``` `unsigned int foo : 1;` would be more appropriate here.
