[cpp]
// This function is environment specialized on "c++<purpose>*".
void takeAnyObject(uno::Reference<...> const & rObj) {
// We need to remember the callers environment, to "map-out/in" // the parameters and return values properly. uno::Environment outerEnv(uno::getCurrent());
// We now activate (enter) the "c++:unsafe" environment.
// Note: Any other environment suiteable for "MyUnsafeObject" would work as well.
cppu::EnvGuard unsafeGuard(uno::Environment(rtl::OUString(RTL_CONSTASCII_PARAM("c++:unsafe"))));
// We "mapIn" the parameter. uno::Reference<...> unsafeEnv_Obj.set(cppu::mapIn(rObj, outerEnv), SAL_NO_ACQUIRE);
// MyUnsafeObj has a C++ OBI and is thread-unsafe unsafeEnv_Obj->set(new MyUnsafeObject());
