Multiple declarations in a C++ namespace

I'm trying to bind to some C++ code, but when I compile the D side, there are errors. Here's my reduced test case: // C++ namespace ns { void func1(); void func2(); } // D module cpp; extern(C++, ns) void func1(); extern(C++, ns) void func2() dmd says:cpp_test.d(4): Error: namespace cpp.ns

Binding non-trivial C++ structs

To make my C++ binding life easier, I wrote a small string structure [1] in C++ to use instead of std::string and produced the D declarations for some of it [2]. (It's not that complicated, I promise.) The important properties of this struct are that it has a non-trivial copy constructor and a de

Passing myself, a struct, as a C callback context

I'm registering a callback with some C code. The simplified story is here, but the actual code is on GitHub [1] at the end if you care. The call looks something like this. void register(void(*fp)(void*), void* context); I have a class that holds state for the callback and registers itself: fin
