RE: Get the function value

["Björklund, Peter" <Peter.Bjorklund@...>]

Interesting code.
But what I want to do is keep the value, so I can issue a lua_call() later
on.

You don't get the function name, you get the function. You can then call
it; see below

> How do I get the function value from the stack?

-----------------------------------
Sample Lua code:

function onTimer()
     doStuff();
end

function onInit()
     -- This is a C function
     setTimer( 5.0, onTimer );
end

----------------------------------
C code:

static int setTimer(lua_State *L)
{
     if ( lua_isnumber( L, 1 ) )
          g_waitTime = lua_tonumber( L, 1 );

     // lua_typename( L, lua_type( L, 2 ) )
     // returns "function" which is what I want :)

/// here is a simple way of doing it
          lua_settop(L, 2);        /* make sure there's no more on the
stack */
          lua_rawcall(L, 0, 0);    /* no arguments, no return values */
///

/* who cares what the name is?
     g_functionName = // How do I get this parameter?
*/
     return 0;
}
