D can't import C header files. And I don't think such a feature 
is planned right now.

You have to translate the C declarations to D, both struct and 
function. You can do that either manually or using some tool.

If you go the manual route, there's a page on that:

For tools, if you're not happy with htod, maybe DStep works 
better:
