FYI, you can also declare and call native Win32 API functions directly
from Eagle, e.g.:

```
set module [library load kernel32.dll]

set function [library declare -functionname GetStdHandle \
    -returntype IntPtr -parametertypes [list int32] -module $module]

set STD_OUTPUT_HANDLE -11; # constant from "WinBase.h"
set handle [library call $function $STD_OUTPUT_HANDLE]
```
