Usage of GetThumbnail (?)

[daniel-prause]

Hi there!

How is one supposed to get IThumbnailCache respectively
pub unsafe fn GetThumbnail(&self, pshellitem: P0, cxyrequestedthumbsize: u32, flags: WTS_FLAGS, ppvthumb: ::core::option::Option<*mut ::core::option::Option>, poutflags: ::core::option::Option<*mut WTS_CACHEFLAGS>, pthumbnailid: ::core::option::Option<*mut WTS_THUMBNAILID>) -> ::windows::core::Result<()>

to work? Could anyone provide an example?
