NAMEares_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);

---

DESCRIPTIONThe 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 VALUESares_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.
