.TH ARES_FREE_HOSTENT 3 "23 July 1998"
.SH NAME
ares_free_hostent \- Free host structure allocated by ares functions
.SH SYNOPSIS
.nf
#include <ares.h>

void ares_free_hostent(struct hostent *\fIhost\fP)
.fi
.SH DESCRIPTION
The
.I ares_free_hostent
function frees a
.B struct hostent
allocated by one of the functions \fIares_parse_a_reply(3)\fP,
\fIares_parse_aaaa_reply(3)\fP, or \fIares_parse_ptr_reply(3)\fP.
.SH NOTES
It is not necessary (and is not correct) to free the host structure passed to
the callback functions for \fIares_gethostbyname(3)\fP or
\fIares_gethostbyaddr(3)\fP. c-ares will automatically free such host
structures when the callback returns.
