Examples

These statements test whether the field identified by fid is a
global variable object. If it is, its value is set to another global
variable object:

fid = session -&gt; GetGlobalVarID("obj2_gvar");
   if (session -&gt; IsGlobalVarObject(fid))
   {
      obj_val = session -&gt; GetObjectGlobalVar(fid,
         isNull);
      cls = session -&gt; GetClass(obj_val);
      fid = session -&gt; GetFieldID(cls, "text");
      s_val = session -&gt; GetStringField(obj_val, fid,
         isNull);
      mystr = session -&gt; GetString(s_val);
      // Set the value of obj2_gvar to obj1_gvar
      fid = session -&gt; GetGlobalVarID("obj1_gvar");
      session -&gt; SetObjectGlobalVar(fid, obj_val);
   }
