<h2 id="author">Host Info<br/>(libbobcat-dev_4.08.02-x.tar.gz)</h2>
<h2 id="date">2005-2017</h2>


<p>
<h2 >NAME</h2>FBB::Hostname - Contains name/address info about a host
<p>
<h2 >SYNOPSIS</h2>
    <strong >#include &lt;bobcat/hostname&gt;</strong><br/>
    Linking option: <em >-lbobcat</em> 
<p>
<h2 >DESCRIPTION</h2>
    <strong >FBB::Hostname</strong> objects inherit from <em >Hostent</em>, and offers information
about a host, like <strong >Hostent</strong>. Apart from being initialized by a hostname or
host address, they can also be initialized by a <strong >FBB::InetAddress</strong>
object. Most of the functionality of an <strong >FBB::Hostname</strong> object is available
through its parent-class <strong >FBB::Hostent</strong>.
<p>
<h2 >NAMESPACE</h2>
    <strong >FBB</strong><br/>
    All constructors, members, operators and manipulators, mentioned in this
man-page, are defined in the namespace <strong >FBB</strong>.
<p>
<h2 >INHERITS FROM</h2>
    <strong >FBB::Hostent</strong>
<p>
<h2 >CONSTRUCTORS</h2>
    <ul>
    <li> <strong >Hostname()</strong>:<br/>
        The default constructor initializes an empty <strong >FBB::Hostname</strong> object.
    <li> <strong >Hostname((std::string const &amp;host))</strong>:<br/>
        This constructor initializes an <strong >FBB::Hostname</strong> object from a string
representing the name or dotted decimal address of a host. An <strong >FBB::Exception</strong>
object is thrown if the hostname information could not be retrieved.
    <li> <strong >Hostname(InetAddress const &amp;inetAddress)</strong>:<br/>
        This constructor initializes an <strong >FBB::Hostname</strong> object from an
<strong >InetAddress</strong> object. An <strong >FBB::Exception</strong>
object is thrown if the hostname information could not be retrieved.
    </ul>
        The copy constructor is available.
<p>
<h2 >MEMBER FUNCTIONS</h2>
     All members of <strong >FBB::Hostent</strong> are available, as <strong >FBB::Hostname</strong>
inherits from this class. There are no additional members.
<p>
<h2 >EXAMPLE</h2>
    <pre >

            cout &lt;&lt; "Adresses:\n";
            for (size_t idx = 0; idx &lt; h.nAddresses(); idx++)
                cout &lt;&lt; h.dottedDecimalAddress(idx) &lt;&lt; " ";
