activex - npapi wrap multi control

Question

I want to wrap some activex dll to npapi. An ActiveX DLL can contain many controls, just like the one I'm going to wrap.

Can a npapi dll contain many controls? I know the npapi control is working like:

x-application/x-...

It just seems that the npapi dll can't wrap many controls, so I must split the controls in the activex dll, but I don't think it's a good idea because there are some public data structs.

Is it possible to have a npapi dll with multiple controls?

Answer 1

是的，NPAPI 插件可以支持多种 mimetype，所有流行的插件实际上都不止一种（例如about:plugins在 Firefox 中检查）。

为插件指定 mimetype 的地方都支持指定多个 mimetype。
NPP_New()并NPP_NewStream()接收NPMIMEType您可以检查的参数。
