const char* ub_event_get_version | ( | void | ) |
Returns event-base type.
Could be "mini-event", "winsock-event" for the daemon compile, and will be "pluggable-event<PACKAGE_VERSION>" for libunbound.

struct ub_event_base* ub_default_event_base | ( | int | sigs, |
time_t * | time_secs, | ||
struct timeval * | time_tv | ||
) |
Return a default event base.
In the daemon this will be the only event bases used.

struct event_base* ub_libevent_get_event_base | ( | struct ub_event_base * | base | ) |
