firefox - js-ctypes：从 Windows DLL 加载 nsISupports

Question

是否可以使用js-ctypes调用 Windows DLL 并让它返回一个 nsISupports 实例？Windows DLL 执行 XPCOMGlue，但不需要 NSModule，我希望我可以改进注册过程。我希望定义了一个 ctypes.nsISupports 类型用作返回值，所以如果可能的话，我该如何声明调用？

Answer 1

From my reading and experimentation, no, it doesn't look like you can. However, you could do the next best thing.

1. Create a win32 DLL exporting plain "C" symbols.

2. Create a "wrapper" XPCom component using JavaScript.

3. Plumb each plain "C" function exported by the DLL into the JavaScript object.

Possible improvement: create a generic JavaScript shim that does the plumbing automatically.
