|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
.nf
|
|
|
|
|
.B #include <ares.h>
|
|
|
|
|
.PP

.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.
