NAME

ares_parse_ptr_reply - Parse a reply to a DNS query of type PTR into a hostent

SYNOPSIS

#include <ares.h>

int ares_parse_ptr_reply(const unsigned char * abuf , int alen ,
const void * addr , int addrlen ,
int family , struct hostent ** host );

DESCRIPTION

The ares_parse_ptr_reply function parses the response to a query of type PTR into a struct hostent . The parameters abuf and alen give the contents of the response. The parameters addr , addrlen , and family specify which address was queried for; they are not used to verify the response, merely used to fill in the address of the struct hostent . The resulting struct hostent 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.

RETURN VALUES

ares_parse_ptr_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.
