<h1>FBB::ClientSocket(3bobcat)</h1>
<h2>libbobcat-dev_4.01.03-x.tar.gz Client Socket</h2>
<h2>2005-2015</h2>


<p>
<h2>NAME</h2>FBB::ClientSocket - Client Socket connecting to a Server in the Internet
<p>
<h2>SYNOPSIS</h2>
    <strong>#include &lt;bobcat/clientsocket&gt;</strong><br>
    Linking option: <em>-lbobcat</em> 
<p>
<h2>DESCRIPTION</h2>
    An <strong>FBB::ClientSocket</strong> may be constructed to connect to some server
process in the internet. The socket made available by the <strong>FBB:ClientSocket</strong>
may be used to initialize a <strong>std::istream</strong> and/or <strong>std::ostream</strong>. The
<strong>std::istream</strong> is used to read information from the server process to which
the <strong>FBB::ClientSocket</strong> connects, The <strong>std::ostream</strong> is used to send
information to the server process to which the <strong>FBB::ClientSocket</strong> connects.
Since a socket may be considered a <em>file descriptor</em> the available
<strong>FBB::IFdStream</strong>, <strong>FBB::IFdStreamBuf</strong>, <strong>FBB::OFdStream</strong>, and
<strong>FBB::OFdStreamBuf</strong> classes may be used profitably here. Note that having
available a socket does not mean that this defines the communication
protocol. It is (still) the responsibility of the programmer to comply with an
existing protocol or to implement a tailor-made protocol. The latter situation
implies that the sequence of input- and output operations is defined by the
programmer. 
<p>
A Unix Domain client socket can be defined using
<em>FBB::LocalClientSocket</em>.
<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::SocketBase</strong>
<p>
<h2>CONSTRUCTOR</h2>
    <ul>
    <li> <strong>ClientSocket(std::string const &amp;host, uint16_t port)</strong>:<br>
        This constructor initializes an <strong>FBB::ClientSocket</strong> object,
preparing it for a connection to the specified port at the given host.  An
<strong>FBB::Exception</strong> is thrown if the socket could not be constructed. The
construction of the socket does not mean that a connection has actually been
established. In order to connect to the server, the member <strong>connect()</strong> (see
below) should be used.
    </ul>
    The copy constructor is not available.
<p>
<h2>MEMBER FUNCTIONS</h2>
     All members of <strong>FBB::SocketBase</strong> (and thus of <strong>FBB::InetAddress</strong>) are
available, as <strong>FBB::ClientSocket</strong> inherits from these classes.
    <ul>
    <li> <strong>int connect()</strong>:<br>
        This member returns a socket that can be used to communicate with the
server process. An <strong>FBB::Exception</strong> exception is thrown if the connection could
not be established or if the <strong>SocketBase</strong> base class could not properly be
constructed.
    </ul>
<p>
<h2>EXAMPLE</h2>
    See also the <strong>serversocket</strong>(3bobcat) example.
