Destroy a resolver channel
#include <ares.h> void ares_destroy(ares_channel channel)
The ares_destroy function destroys the name service channel identified by channel, freeing all memory and closing all sockets used by the channel. ares_destroy invokes the callbacks for each pending query on the channel, passing a status of ARES_EDESTRUCTION. These calls give the callbacks a chance to clean up any state which might have been stored in their arguments. A callback must not add new requests to a channel being destroyed.
