.SH NAME
ares_free_hostent \- Free host structure allocated by ares functions
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B 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
.I ares_parse_a_reply
or
.IR ares_parse_ptr_reply .
.SH SEE ALSO
.BR ares_parse_a_reply (3),
.BR ares_parse_ptr_reply (3)
.SH NOTES
It is not necessary (and is not correct) to free the host structure
passed to the callback functions for
.I ares_gethostbyname
or
.IR ares_gethostbyaddr .
The ares library will automatically free such host structures when the
callback returns.
