.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. |
