What would be the smartest solution?
If you can change the signature of foo just add a extern(c) to
the function pointer declaration.
Otherwise just wrap the SDL_FreeSurface call into a delegate on
the caller side.
You mean like this?
----
void foo(T)(extern(C) void function(T*) func) {
}
----
That prints: Error: basic type expected, not extern
