ARES_DESTROY(3) Library Functions Manual ARES_DESTROY(3)

ares_destroy - Destroy a resolver channel

#include <ares.h>
void ares_destroy(ares_channel_t *channel)

The ares_destroy(3) function destroys the name service channel identified by channel, freeing all memory and closing all sockets used by the channel.

ares_destroy(3) 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.

There is no ability to make this function thread-safe. No additional calls using this channel may be made once this function is called.
