Look at the manual [1] and search for get() member and get_pointer free function. [1] http://www.boost.org/doc/libs/1_52_0/libs/smart_ptr/shared_ptr.htm Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

shared_ptr<int> p; p.get();
But make sure the function doesn't store this raw pointer, otherwise it would defeat the whole purpose of shared_ptr.
More specifically, make sure that you have a shared_ptr<> in scope for the entire time the raw pointer is in scope. Failure to do so will surely result in badness at some point. -- Chris Cleeland
