<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>The extended socket class. </p>
<p>This class should be used instead of <a class="el" href="classKSocket.html" title="A TCP/IP client socket.">KSocket</a> whenever the user needs fine-grained control over the socket being created. Unlike <a class="el" href="classKSocket.html" title="A TCP/IP client socket.">KSocket</a>, which does everything at once, without much intervention, <a class="el" href="classKExtendedSocket.html" title="The extended socket class.">KExtendedSocket</a> allows intervention at every step of the process and the setting of parameters.</p>
<p>This class allows for the creation of both server and client sockets. The only difference is that the passiveSocket flag must be passed either to the constructor or to <a class="el" href="classKExtendedSocket.html#aa1b335227407fa6346c9168cfb709f3a" title="Sets the given flags.">setSocketFlags()</a>. If passiveSocket is used, the class will enable functions <a class="el" href="classKExtendedSocket.html#ad2c84c8686c5abd247bff0f1c25bbc46" title="Place the socket in listen mode.">listen()</a> and <a class="el" href="classKExtendedSocket.html#afa5900a11efa44d54187da01add86b1d" title="Accepts an incoming connection from the socket.">accept()</a> and related signals, and will also disable <a class="el" href="classKExtendedSocket.html#a6a005f748384b0ebb918959a803a04bd" title="Reads a block of data from the socket.">readBlock()</a> and <a class="el" href="classKExtendedSocket.html#a7e47772fd24e519ac1a570fbfb85f2ef" title="Writes a block of data to the socket.">writeBlock()</a>.</p>
<p>To create a Unix socket, one would pass flag unixSocket to the constructor or <a class="el" href="classKExtendedSocket.html#aa1b335227407fa6346c9168cfb709f3a" title="Sets the given flags.">setSocketFlags()</a>. The hostname and service/port can be set to whatever is necessary. If no hostname is given, but a service/port is, the socket created will be implementation dependant (usually in /tmp). In any other case, the fields will be concatenated.</p>
<p>To create an Internet socket, inetSocket flag can be used. If, on the other hand a specific IP protocol is desired, ipv4Socket and/or ipv6Socket can be used.</p>
<p>Note that the socket type selection flags are cumulative. One could select Unix and Internet sockets by using unixSocket | inetSocket. Or, for instance, to make sure only IPv4 and IPv6 sockets are selected, even if future implementations support newer IP protocols, ipv4Socket | ipv6Socket is your guy.</p>

<p>If the socket is not buffered, this function will simply call the underlying write method. This means that the function might block if that method blocks as well.
