asynchronous DNS resolver
libasr provides a simple interface for asynchronous address resolution and nameserver querying. It should be used in place of the classical resolver functions of libc when blocking is not desirable. libasr is thread-safe and lock-free internally except for the two atypical use cases listed in asr_run(3).
