ARES\_PARSE\_SOA\_REPLY(3) Library Functions Manual ARES\_PARSE\_SOA\_REPLY(3)

# [NAME](#NAME)

ares\_parse\_soa\_reply - Parse a reply to a DNS query of type SOA

# [SYNOPSIS](#SYNOPSIS)

```
#include <ares.h>
int ares_parse_soa_reply(const unsigned char* abuf, int alen,


                         struct ares_soa_reply** soa_out);
```

# [DESCRIPTION](#DESCRIPTION)

The **ares\_parse\_soa\_reply** function parses the response to a query of type SOA into a *struct ares\_soa\_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 *soa\_out*. It is the caller's responsibility to free the resulting *soa\_out* structure when it is no longer needed using the function [**ares\_free\_data(3)**](/man/os/c-ares/ares_free_data.3).

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

```
struct ares_soa_reply {
	char *nsname;
	char *hostmaster;
	unsigned int serial;
	unsigned int refresh;
	unsigned int retry;
	unsigned int expire;
	unsigned int minttl;
};
```

# [RETURN VALUES](#RETURN_VALUES)

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

[**ARES\_SUCCESS**](#ARES_SUCCESS)

The response was successfully parsed.

[**ARES\_EBADRESP**](#ARES_EBADRESP)

The response was malformatted.

[**ARES\_ENODATA**](#ARES_ENODATA)

The response did not contain an answer to the query.
