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.
