enable_shared_from_this::shared_from_this
Generates a shared_ptr.
shared_ptr<Ty> shared_from_this();
shared_ptr<const Ty> shared_from_this() const;
Remarks
The member functions each return a shared_ptr Class object that owns *(Ty*)this.
Example
// std_tr1__memory__shared_from_this.cpp
// compile with: /EHsc
#include <memory>
#include <iostream>
struct base
: public std::enable_shared_from_this<base>
{
int val;
};
int main()
{
std::shared_ptr<base> sp0(new base);
std::shared_ptr<base> sp1 = sp0->shared_from_this();
sp0->val = 3;
std::cout << "sp1->val == " << sp1->val << std::endl;
return (0);
}
sp1->val == 3
