ARES_PARSE_A_REPLY(3) FreeBSD Library Functions Manual ARES_PARSE_A_REPLY(3)

ares_parse_a_reply - Parse a reply to a DNS query of type A into a hostent

#include <ares.h>
int ares_parse_a_reply(const unsigned char *abuf, int alen,
	struct hostent **host);

The ares_parse_a_reply function parses the response to a query of type A into a struct hostent. 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 host. It is the caller's responsibility to free the resulting host structure using ares_free_hostent(3) when it is no longer needed.

ares_parse_a_reply can return any of the following values:
ARES_SUCCESS
The response was successfully parsed.
ARES_EBADRESP
The response was malformatted.
ARES_ENODATA
The response did not contain an answer to the query.
ARES_ENOMEM
Memory was exhausted.

ares_gethostbyname(3), ares_free_hostent(3)
