The C++11 function std::bind() fixes some or all arguments of a function object, returning another function object that takes fewer arguments.

std::bind performs Partial Function Application of arbitrary C++ function objects, fixing some or all arguments of a function object and returning another function object that takes fewer arguments.

The function is based on boost::bind() which originated in the library (see ) and an earlier version was included in as std::tr1::bind().

Binding to privately inherited member function

I'd like to std::bind to a member function from a private base class, made "public" with a using-declaration in the derived class. Calling the function directly works, but it seems binding or using member function pointers doesn't compile: #include…
