When it's a function parameter you could even make it const(T*):
void hello(const char *name);
--> extern(C) void hello(const(char*) name);

as the pointer itself is passed by value, there's no way it could be
modified by hello. DMD should be able to figure that out and treat
const(char)* exactly the same, but last time I checked it didn't.

There are different solutions. Some people prefer to make those
templates, so the binding can be used as a .di file and doesn't need to
be compiled. Others just use functions and hope the optimizer will
inline it ;-)
