|
** 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).
|
|
** 4. enjoy.
