| ** Author: Justin Frankel | ||
| ** File: asyncdns.h - JNL portable asynchronous DNS interface | ||
| ** License: see jnetlib.h | ||
| ** | ||
| ** Usage: | ||
| ** 1. Create JNL_AsyncDNS object, optionally with the number of cache entries. | ||
| ** 2. call resolve() to resolve a hostname into an address. The return value of | ||
| ** resolve is 0 on success (host successfully resolved), 1 on wait (meaning | ||
| ** try calling resolve() with the same hostname in a few hundred milliseconds | ||
| ** or so), or -1 on error (i.e. the host can't resolve). | ||
| ** 3. call reverse() to do reverse dns (ala resolve()). | ||
| ** 4. enjoy. | ||
