<H2>DESCRIPTION</H2>

These functions do various comparisons and tests on the
<I>ip_address</I>

type and
<I>ip_subnet</I>

types.
<P>

<I>Sameaddr</I>

returns
non-zero
if addresses
<I>a</I>

and
<I>b</I>

are identical,
and
<B>0</B>

otherwise.
Addresses of different families are never identical.
<P>

<I>Addrcmp</I>

returns
<B>-1</B>,

<B>0</B>,

or
<B>1</B>

respectively
if address
<I>a</I>

is less than, equal to, or greater than
<I>b</I>.

If they are not of the same address family,
they are never equal;
the ordering reported in this case is arbitrary
(and probably not useful) but consistent.
<P>

<I>Samesubnet</I>

returns
non-zero
if subnets
<I>a</I>

and
<I>b</I>

are identical,
and
<B>0</B>

otherwise.
Subnets of different address families are never identical.
<P>

<I>Addrinsubnet</I>

returns
non-zero
if address
<I>a</I>

is within subnet
<I>s</I>

and
<B>0</B>

otherwise.
An address is never within a
subnet of a different address family.
<P>

<I>Subnetinsubnet</I>

returns
non-zero
if subnet
<I>a</I>

is a subset of subnet
<I>b</I>

and
<B>0</B>

otherwise.
A subnet is deemed to be a subset of itself.
A subnet is never a subset of another
subnet if their address families differ.
<P>

<I>Subnetishost</I>

returns
non-zero
if subnet
<I>s</I>

is in fact only a single host,
and
<B>0</B>

otherwise.
<P>

<I>Samesaid</I>

returns
non-zero
if SA IDs
<I>a</I>

and
<I>b</I>

are identical,
and
<B>0</B>

otherwise.
<P>

<I>Sameaddrtype</I>

returns
non-zero
if addresses
<I>a</I>

and
<I>b</I>

are of the same address family,
and
<B>0</B>

otherwise.
<P>

<I>Samesubnettype</I>

returns
non-zero
if subnets
<I>a</I>

and
<I>b</I>

are of the same address family,
and
<B>0</B>

otherwise.
