Subj : Re: Iterate all functions in script

I get a vector with 15 itmes in it now, but not of the id's pass the
JSVAL_IS_FUNCTION check.
When I forgo this check I get errors that state "'string' is not a function"
when I call JS_ValueToFunction.

Any insights would be great.

// code
// evaluated the script with JS_ExecuteScript before this.
  JSIdArray* ida = JS_Enumerate(m_pContext, m_pGlobal);
  if (ida)
  {
   for (int i = 0, j = ida->length; i < j; i++)
   {
    jsid id = ida->vector[i];

    if (!JSVAL_IS_INT(id))
    {
     jsval val;
     if ( JS_IdToValue(m_pContext, id, &val) == JS_TRUE
      && JSVAL_IS_FUNCTION(m_pContext, val))
     {
      JSFunction* pfun = JS_ValueToFunction(m_pContext, val);
      if (pfun)
      {
       JSString* pjssFunName = JS_GetFunctionId(pfun);
       if (pjssFunName)
       {
        CString strFunctionName(JS_GetStringBytes(pjssFunName));

        int i = 0;
       }
      }
     } // got value
    } // is pointer
   } // for

   JS_DestroyIdArray(m_pContext, ida);
  } // if valid id array

Ultimate goal is to build a list of all the function names defined in the
script.
