   Display a single variable:
   <td>IP Address</td>
   <td> <!--VARIABLE IPCAST(gConfigRec.ip_Addr) --> </td>
   <td> <!--VARIABLE IPCAST(EthernetIP) --> </td>

   Display the result of an equation:
   Tick count is : <!--VARIABLE TimeTick/TICKS_PER_SECOND --> seconds

Function Call

The FUNCTIONCALL tag passes the socket fd and URL to a 'C' function in your application code:


HTML Source Code:
<!--FUNCTIONCALL Foo -->

Function Call with Parameters

The VARIABLE tag can be used to call a 'C++' function with multiple parameters.
The example below shows 2 parameters:


HTML Source Code:
<!--VARIABLE FooWithParameters( fd, 123 ) -->
