Run this code
#include <iostream> #include <memory> struct Foo { Foo() { std::cout << "Foo...\n"; } ~Foo() { std::cout << "~Foo...\n"; } }; struct D { void bar() { std::cout << "Call deleter D::bar()...\n"; } void operator()(Foo* p) const { std::cout << "Call delete for Foo object...\n"; delete p; } }; int main() { std::unique_ptr<Foo, D> up(new Foo(), D()); D& del = up.get_deleter(); del.bar(); }
Output:
Foo... Call deleter D::bar()... Call delete for Foo object... ~Foo...
