ARES\_DESTROY(3) Library Functions Manual ARES\_DESTROY(3)

# [NAME](#NAME)

ares\_destroy - Destroy a resolver channel

# [SYNOPSIS](#SYNOPSIS)

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

# [DESCRIPTION](#DESCRIPTION)

The [**ares\_destroy(3)**](/man/os/c-ares/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)**](/man/os/c-ares/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.
