- Timo Teras changed the reason code used in the resolve callback done when

  fails to get inited by other means. This fixes a case of when the c-ares

  init fails when internet access is fone.

- Timo Teras changed the reason code used in the resolve callback done when

  ares_cancel() is used, to be ARES_ECANCELLED instead of ARES_ETIMEOUT to

  better allow the callback to know what's happening.

* 14 Jul 2009 (Guenter Knauf)

- renamed generated config.h to ares_config.h to avoid any future clashes

  with config.h from other projects.

 o a build-time configured ares_socklen_t is now used instead of socklen_t

 o new ares_library_init() and ares_library_cleanup() functions

 o new --enable-curldebug configure option

 o ARES_ECANCELLED is now sent as reason for ares_cancel()

Fixed:

The \fBares_cancel\fP function cancels all lookups/requests made on the the

name service channel identified by \fIchannel\fP.  \fBares_cancel\fP invokes

the callbacks for each pending query on the channel, passing a status of

.BR ARES_ETIMEOUT .

.BR ARES_ECANCELLED .

These calls give the callbacks a chance to clean up any state which

might have been stored in their arguments.

.SH NOTES

This function was added in c-ares 1.2.0

c-ares 1.6.0 and earlier pass a status of
