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.
