<p>The <span class="lang">npserver</span> class is used on the server side of 
an interprocess communication channel. It listens to connections on the specified 
named pipe or a local UNIX socket and for each connection provides a <span class="lang">namedpipe</span> 
object for exchanging data with the peer.</p>
<p>Please, read the introduction to <a href="streams.namedpipe.html">namedpipe</a> 
first.</p>
<p><span class="def">npserver::npserver(string pipename)</span> creates a named 
pipe server object. The named pipe or a local socket is actually created during 
the first call to <span class="lang">serve()</span> for this object.</p>
<p><span class="def">bool npserver::serve(namedpipe& client, int timeout = 
-1)</span> polls the pipe for connection requests. If there is a connection request 
from a client, <span class="lang">serve()</span> opens and prepares the supplied 
namedpipe object for communicating with the client, i.e. <span class="lang">client</span> 
will be active upon return from <span class="lang">serve()</span>. The second 
optional parameter <span class="lang">timeout</span> specifies the amount of time 
in milliseconds to wait for a connection request. If timeout is 0 <span class="lang">serve()</span> 
will return immediately; if it's -1 <span class="lang">serve()</span> will wait 
infinitely. This function returns <span class="lang">true</span> if there is a 
connection request and the <span class="lang">client</span> object is active, 
or <span class="lang">false</span> if the call has timed out.</p>
