Callbacks are an essential part of interfacing with C code.  The "Interfacing to C" document comes close to telling you how to setup a callback but assumes the reader knows about the "function" keyword already.  In the section where it says:

"C code can correspondingly call D functions, if the D functions use an attribute that is compatible with the C compiler, most likely the extern (C)..."

There should be an example showing how to setup the binding like so:

  extern (C) void registerSomeCallback(void function(int,int) yourFunc);

And then it should hyperlink to the "Delegates, Function Pointers, and Closures" section in /function.html.

I'd be glad to make these changes myself if you like.
