The din typemap is used for converting function parameter types from the type used in the proxy module or class to the type used in the intermediary D module (the $dinput macro is replaced).
-The dout typemap is used for converting function return values from the return type used in the intermediary D module to the type returned by the proxy function. The $excode special variable in dout typemaps is replaced by the excode typemap attribute code if the method can throw any exceptions from unmanaged code, otherwise by nothing (the $imcall and $owner macros are replaced).

The code from the ddirectorin and ddirectorout typemaps is used for conversion in director callback functions. Arguments are converted to the type used in the proxy class method they are calling by using the code from ddirectorin, the proxy class method return value is converted to the type the C++ code expects via the ddirectorout typemap (the $dcall and $winput macros are replaced).
