std::bind and overloaded function

Question

Please refer the following code snippet. I want to use the std::bind for overloaded function foobar. It calls only the method with no arguments.

You need to use placeholders for the unbound arguments:

auto a2 = std::bind(static_cast<void(Client::*)(int)>(&Client::foobar), cl,
                    std::placeholders::_1);
a2(5);

You can also perform the binding with a lambda capture (note that this is binds cl by reference, not by value):

auto a2 = [&](int i) { cl.foobar(i); };
