It bounds itself to a specified port/address and waits until a connection request is received from a client host. For each connection request a server application performs some actions and returns to the waiting state. For better performance your daemon may start a new thread for each client connection.</p><p><span class="lang">ipstmserver</span> can generate exceptions of type <span class="lang">(estream*)</span> with a corresponding error code and a message string.</p><p><span class="def">ipstmserver::ipstmserver()</span> constructs an <span class="lang">ipstmserver</span> object.</p><p><span class="def">void ipstmserver::bind(ipaddress ip, int port)</span> binds the server to the specified local IP address and port number. This function can be called multiple times for different local addresses and port numbers.</p><p><span class="def">void ipstmserver::bindall(int port)</span> binds the server to all local IP address on the specified port number. Can be called multiple times for different port numbers.</p><p><span class="def">bool ipstmserver::poll(int bindnum = -1, int timeout = 0)</span> polls the listening sockets for connection requests. <span class="lang">Bindnum</span> specifies the socket number to test. The numbering of bound sockets corresponds to the order in which functions <span class="lang">bind()</span> or <span class="lang">bindall()</span> were called, starting from 0. If <span class="lang">bindnum</span> is -1 <span class="lang">poll()</span> will test all sockets. The second parameter <span class="lang">timeout</span> specifies the amount of time in milliseconds to wait for a connection request. If <span class="lang">timeout</span> is 0 <span class="lang">poll()</span> will return immediately; if it's -1 <span class="lang">poll()</span> will wait infinitely. This function returns <span class="lang">true</span> if there is a new connection request waiting for processing.</p><p><span class="def">bool ipstmserver::serve(ipstream& client, int bindnum = -1, int timeout = -1)</span> polls the specified bound sockets for connection requests. If there is a connection request, <span class="lang">serve()</span> opens and prepares the supplied <span class="lang">ipstream</span> object for communicating with the client, i.e. <span class="lang">client</span> will be active upon return from <span class="lang">serve()</span> and will contain the peer IP address and the port number. The meanings of <span class="lang">bindnum</span> and <span class="lang">timeout</span> are the same as for <span class="lang">poll()</span> except that the default value for <span class="lang">timeout</span> in this case is -1, i.e. wait infinitely. This function returns <span class="lang">true</span> if there is a new connection request and <span class="lang">client</span> is active, or <span class="lang">false</span> if the call has timed out.</p><p class="seealso">See also: <a href="inet.ipstream.html">ipstream</a>, <a href="inet.utils.html">Utilities</a>, <a href="inet.examples.html">Examples</a></p><!-- #EndEditable --> <hr size="1"><a href="../index.html" class="ns">PTypes home</a></body><!-- #EndTemplate --></html>⌨️ 快捷键说明
