SYNOPSIS
#include <ares.h>
int ares_parse_a_reply(const unsigned char *abuf, int alen,
struct hostent **host,
struct ares_addrttl *addrttls, int *naddrttls);
DESCRIPTION
The ares_parse_a_reply function parses the response to a query of type A into a struct hostent and/or an array of struct ares_addrttls. 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, if host is nonnull. It is the caller's responsibility to free the resulting host structure using ares_free_hostent(3) when it is no longer needed.If addrttls and naddrttls are both nonnull, then up to *naddrttls struct ares_addrttl records are stored in the array pointed to by addrttls, and then *naddrttls is set to the number of records so stored. Note that the memory for these records is supplied by the caller.
RETURN VALUES
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.
