Hi All,

I have created a new shared_ptr class called shared_ptr_embedded. This is
based on the code for intrusive_ptr but differs in one important
aspect. The struct/class pointed to is required to be derived from
shared_ptr_count. The latter class contains an 'int count_' and methods
for adding and removing references. This allows you to have the count
embedded in your primary data, rather than having a separate allocation for
count as shared_ptr does.

Here is an example:

#include <boost/shared_ptr_embedded.hpp>

class SharedName
         struct Data : public boost::shared_ptr_count
                 std::string name_;
         boost::shared_ptr_embedded<Data> data_;
         SharedName(std::string n) : data_(new Data) { data_->name_ = n; }
         const std::string& GetName() { return data_->name_; }
         SharedName& operator=(std::string n) { data_->name_ = n; return
*this; }

I think this would be a valuable addition to the boost suite. How would I
go about submitting this?
