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);

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