ARES_FREE_HOSTENT(3)							     ARES_FREE_HOSTENT(3)

NAME
       ares_free_hostent - Free host structure allocated by ares functions

SYNOPSIS
       #include <ares.h>

       void ares_free_hostent(struct hostent *host)

DESCRIPTION
       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).

NOTES
       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.

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