</dl><a name="new_service_intro"><h3>Introduction</h3></a>
<p>
A service is set of functionnalities provided by a server. The class <a class="el" href="class_NLNET__IService.html">NLNET::IService</a> is the base class of all services.
<p>
<a class="el" href="class_NLNET__IService.html">NLNET::IService</a> performs automatically the basic functionnalities of any service, such as registration to the Naming Service, server start-up and shutdown.
<p>
<a class="el" href="class_NLNET__IService.html">NLNET::IService</a> is located in NeL, but user-defined services are located in /code/nelns.
<p>
<a name="new_service"><h3>How to create a user-defined service ?</h3></a>
<p>
<ol>
<li>Create a class inherited from <a class="el" href="class_NLNET__IService.html">NLNET::IService</a> (optional).<li>Create an array of callbacks, called <em><a class="el" href="net_layer3_client_cpp.html#a0">CallbackArray</a></em>. Example : <div class="fragment"><pre><font class="keywordtype">void</font> cbProcessConnection( CMessage& message, TSockId from, CCallbackNetBase& nb )<font class="keyword">
</font><font class="keyword"></font>{
<font class="comment">// Process here</font>
}
<font class="keywordtype">void</font> cbProcessReceivedMsg( CMessage& message, TSockId from, CCallbackNetBase& nb )<font class="keyword">
</font><font class="keyword"></font>{
<font class="comment">// Process incoming message here</font>
}
TCallbackItem CallbackArray[] =
{
{ <font class="stringliteral">"LOG"</font>, cbProcessReceivedMsg },
{ <font class="stringliteral">"C"</font>, cbProcessConnection }
};</div></pre><li>Reimplement the methods <a class="el" href="nel_3dsmax_shared_cpp.html#a2">init</a>(), update() and release() if you need to (optional). After each call to update(), CNetManager::update() is automatically called, so that the server can handle incoming messages (by calling the callbacks) and flush buffers of outgoing data.<li>Add in your source file the NLNET_SERVICE_MAIN line, with the following arguments :</ol>
<ul>
<li>The name of your class (or <a class="el" href="class_NLNET__IService.html">NLNET::IService</a> if you do not inherit from it (*))<li>The short name of your service<li>Its long name<li>The chosen port number (set it to 0 for "auto-assigned by the naming service")<li>The callback array</ul>
Example: <div class="fragment"><pre><a class="code" href="service_h.html#a0">NLNET_SERVICE_MAIN</a>( CMyService, <font class="stringliteral">"MS"</font>, <font class="stringliteral">"my_service"</font>, 0, CallbackArray );</div></pre>
<p>
(*) Note: if your service does nothing else calling your callbacks, i.e. <a class="el" href="nel_3dsmax_shared_cpp.html#a2">init</a>(), update() and release() are empty, you don't need to create a new class : you can use IService directly and write IService instead of CMyService.
<p>
To run your service, create a file "<service_long_name>.cfg" in the working directory, containing the location of your naming service.
<p>
Example: my_service.cfg: <div class="fragment"><pre>NSHost = <font class="stringliteral">"itsalive.nevrax.org"</font>;
NSPort = 50000;</div></pre>
<p>
<a name="new_services_examples"><h3>Examples</h3></a>
<p>
See the nelns services source code for examples on how to create a class inherited from IService.
