Hi.

According to Witz manual it's possible to call a C++ function in Witz template. Unfortunately there's no example showing how to do that. In one of my source files I defined a trivial function:

void fun(int& i)
{
   i++;
}

and Skylark handler:

SKYLARK(AAA, "aaa")
{
   http("MYVAR", Value(2)); 
   http("MYFUN", fun);
   http.RenderResult("Project_name/aaa");
}

The corresponding aaa.witz template looks like this:

<html>
<body>

$MYVAR
$MYFUN($MYVAR)
$MYVAR

</body>
</html>

I expected to see the following output: 2 3 (old and new value of MYVAR). Instead I got the following error message:

"function nor link not found 'MYFUN'".

I assumed I just had to pass a pointer to my function as a value of shared variable MYFUN to make it visible in Witz template, but apparently that's not how it works. What's the correct way to do it?
