Hi Me and my colleagues have come across an issue when using a shared_ptr. void myFunction(shared_ptr<myClass> const & vp_Pointer) { vp_Pointer->call any non-const function } i.e. a const shared_ptr doesn't prevent anyone from changing the contents to which the pointer points. This makes sense as it behaves like a normal pointer. However, how can I pass a shared pointer into a function such that the data can not be modified? i.e. how can I pass an equivalent of "myClass const *" ? I tried static casting to shared_ptr<const myClass> which works but causes a new constructor to be called which means I loose the efficiency of passing by reference. Any comments of suggestions would be greatly appreciated. Martin Bosticky Software Engineer Action Information Management Ltd. Tel: (01225) 711200 Fax: (01225) 711222 Email: [EMAIL PROTECTED]
