Field Documentation

◆ nat64_prefix_addr

struct sockaddr_storage iter_env::nat64_prefix_addr

NAT64 prefix address, cf.


Referenced by iter_apply_cfg().

◆ target_fetch_policy

int* iter_env::target_fetch_policy

The target fetch policy for each dependency level.

This is described as a simple number (per dependency level): negative numbers (usually just -1) mean fetch-all, 0 means only fetch on demand, and positive numbers mean to fetch at most that many targets. array of max_dependency_depth+1 size.
