ARES_FREE_HOSTENT(3) Library Functions Manual ARES_FREE_HOSTENT(3)

ares_free_hostent - Free host structure allocated by ares functions

#include <ares.h>
void ares_free_hostent(struct hostent *host)

The ares_free_hostent function frees a struct hostent allocated by one of the functions ares_parse_a_reply(3), ares_parse_aaaa_reply(3), or ares_parse_ptr_reply(3).

It is not necessary (and is not correct) to free the host structure passed to the callback functions for ares_gethostbyname(3) or ares_gethostbyaddr(3). c-ares will automatically free such host structures when the callback returns.

ares_parse_a_reply(3), ares_parse_aaaa_reply(3), ares_parse_ptr_reply(3), ares_parse_ns_reply(3)
