Libasr is a FREE asynchronous DNS resolver. The asr_* functions provide a simple interface for asynchronous address resolution and nameserver querying. They should be used in place of the classical resolver functions of libc when blocking is not desirable. event(3) API integration is provided by the event_asr_* functions, which allow to schedule the asynchronous resolver query to run within a libevent event loop. This version is based on the bundled copy found in the OpenSMTPD project.
