Re: [Boost-users] boost::none for boost::shared_ptr

Hello,

Does boost::shared_ptr offer a way to create an empty shared pointer without a lot of typing? Perhaps something analogous to boost::none. I am not using c++11.

Thank you,

Chris

using boost::none; using boost::optional;

// declare f(optional<CSomeReallyLongClassName> Item); g(shared_ptr<CSomeReallyLongClassName> pItem);

// invoke f with empty object f(none);

// invoke g with empty object g(shared_ptr<CSomeReallyLongClassName>());

g(0); Ben
