Here's some code based upon the example at :
http://www.boost.org/doc/libs/1_38_0/libs/smart_ptr/enable_shared_from_this....
class X { public: X() { }; };
template<class X>
class Y: public enable_shared_from_this< Y<X> >
{
public:
shared_ptr< Y<X> > f()
{
return shared_from_this();
}
};
typedef Y<X> templatedY;
int main()
{
shared_ptr<templatedY> p(new Y<X>);
shared_ptr<templatedY> q = p->f();
assert(p == q);
assert(!(p < q || q < p)); // p and q must share ownership
}
compiles with:
$ gcc -o
test -I/usr/local/include/boost-1_38 -lstdc++ -L/usr/local/lib -lboost_system-gcc41-mt
test.cpp
test.cpp: In member function âboost::shared_ptr
