whats the proper way to use/wrap C functions  that expect a error string buffer
e.g.:
somefun(T param1, char* errstr, size_t errstr_size)
 in D ?

dynamic:

auto buf = new char[size];
somefun(param1, buf.ptr, buf.length);
or
somefun(param1, buf.ptr, size);

static:

char[size] buf;
somefun(param1, &buf, size);

somefun(param1, buf.ptr, buf.length);

still works there too. That's the form I prefer to use.
