遇到一个好站点：PInvoke for DotNet

http://www.pinvoke.net/default.aspx/avifil32.AVIFileCreateStream

这个网站里面的东西很全，利用托管方式调用非托管资源，并且有详细的介绍，值得收藏。

AVIFileCreateStream (avifil32)

Type a page name and press Enter. You'll jump to the page if it exists, or you can create it if it doesn't.
To create a page in a module other than avifil32, prefix the name with the module name and a period.
