C++ How do you pass a member function into a functor parameter?

Question

I am using TRI DDS - here is the prototype for the function I am trying to call:

template
dds::sub::cond::ReadCondition::Re         


        

Answer 1

You could use std::bind (see http://en.cppreference.com/w/cpp/utility/functional/bind)

dds::sub::cond::ReadCondition rc(*mp_reader,
                                 dds::sub::status::DataState::any(),
                                 std::bind(&MyClass::do_stuff, this));

Answer 2

You can use a lambda function with a capture.

dds::sub::cond::ReadCondition rc(*mp_reader,
                                 dds::sub::status::DataState::any(),
                                 [this](){ this->do_stuff(); });
