Field Documentation

donotq

struct iter_donotq* iter_env::donotq

A set of inetaddrs that should never be queried.

Referenced by iter_apply_cfg(), iter_deinit(), iter_filter_unsuitable(), and iter_get_mem().

max_dependency_depth

int iter_env::max_dependency_depth

The maximum dependency depth that this resolver will pursue.

Referenced by fetch_fill(), generate_a_aaaa_check(), generate_ns_check(), iter_apply_cfg(), iter_get_mem(), query_for_targets(), and read_fetch_policy().

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.

Referenced by fetch_fill(), iter_apply_cfg(), iter_deinit(), and read_fetch_policy().
