dwrap6<R> method
Binds a cwraped C function taking 6 arguments and returning a plain
(non-struct) value.
R determines the JS->Dart return conversion applied on every call
(see _conv); use void if the C function returns nothing.
Implementation
WF6<R> dwrap6<R>(String name) {
final f = _wn(name, 6);
final c = _conv<R>();
return (a1, a2, a3, a4, a5, a6) => c(f.run([a1, a2, a3, a4, a5, a6]));
}
