The compiler seemed happy with the syntax, but I still get a segmentation
fault. I tried a couple of random permutations of the code below.


void vtkCocoaRenderWindow::SetWindowInfo(char* info)
    {
      //long tmp;
      
      //sscanf(info,"%ld",&tmp);
      int tmp;
      sscanf(info, "%i", &tmp);
      NSMutableDictionary * manager =
        reinterpret_cast<NSMutableDictionary *>(this->GetCocoaManager());
      [manager setObject:reinterpret_cast<id>(tmp)
         forKey:@"DisplayId"];
      //[manager setObject:reinterpret_cast<id>(tmp)
      // forKey:@"WindowId"];
      //[manager setObject:reinterpret_cast<id>(info)
      // forKey:@"DisplayId"];
      //[manager setObject:reinterpret_cast<id>(info)
      // forKey:@"WindowId"];
      vtkWarningMacro("Method not implemented.");
    }
