Thanks H. S. Teoh.
Hmm, still same result though.


     import std.string;

     auto str = toStringz("{\"a\":1}");

     bson_error_t error;

     bson_new_from_json(str, -1, &error);




     extern(C) {
         ...
         bson_t* bson_new_from_json(const char* data, long len, 
bson_error_t* error);
     }
