Libdnsres provides a non-blocking, thread-safe API for resolving DNS names. It requires that your main application is built on top of libevent. The API essentially mirrors the traditional gethostbyname and getaddrinfo interfaces. All return values have been replaced by callbacks instead. The code borrows heavily from the BSD resolver library. In fact, it is an extremely ugly hack to make the BSD resolver library non-blocking and thread-safe without changing the API too much. Although it has not been tested heavily, it should compile on BSD systems and Linux. The library comes with a simple test program that can be use to verify if it works correctly.  [edit]  Less
