<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

|
|

otherwise.
|

<P>
|
|
|
|
<I>Samesubnettype</I>
|
|
|
|
returns
|
|
non-zero
|
|
if subnets
|
|
<I>a</I>
|
|
|
|
and
|
|
<I>b</I>
|
|
|
|
are of the same address family,
