If you know how your C++ compiler mangles functions inside namespaces,
you should be able to hack something together using pragma mangle. I'm
not sure how nice it can be, ideally a UDA (user defined attribute)
should be enough, but I've never used them myself so I don't know if
this is possible:
@Cpp("namespace") void foo(int x);
or even:
@Cpp("namespace")
{
void foo();
void bar();
}
where @Cpp applies extern(C++) and pragma(mangle,
"correctlymangledname"). Anyone knows if this can be done?
That's not currently possible. Have a look at this:
