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><p class="seealso">See also: <a href="streams.namedpipe.html">namedpipe</a>, <a href="inet.examples.html">Networking examples</a></p><!-- #EndEditable --><hr size="1"><a href="../index.html" class="ns">PTypes home</a></body><!-- #EndTemplate --></html> |
