# ares\_parse\_uri\_reply(3)

Parse a reply to a DNS query of type URI

## NAME

ares\_parse\_uri\_reply - Parse a reply to a DNS query of type URI

## SYNOPSIS

```
#include <ares.h>
int ares_parse_uri_reply(const unsigned char* abuf, int alen,
                         struct ares_uri_reply** uri_out);
```

## DESCRIPTION

The *[ares\_parse\_uri\_reply(3)](/ares_parse_uri_reply/3.md)* function parses the response to a query of type URI into a linked list of *struct ares\_uri\_reply* The parameters *abuf* and *alen* give the contents of the response.  The result is stored in allocated memory and a pointer to it stored into the variable pointed to by *uri\_out*. It is the caller's responsibility to free the resulting *uri\_out* structure when it is no longer needed using the function **[ares\_free\_data(3)](/ares_free_data/3.md)**.

The structure  *ares\_uri\_reply* contains the following fields:

```
struct ares_uri_reply {
    struct ares_uri_reply       *next;
    unsigned short              weight;
    unsigned short              priority;
    char                        *uri;
    int                         ttl;
};
```

## RETURN VALUES

**ares\_parse\_uri\_reply** can return any of the following values:

- **ARES\_SUCCESS**

  The response was successfully parsed.

- **ARES\_EBADRESP**

- **ARES\_ENODATA**
