boost::bind is a generalization of the standard C++ functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions.

boost::bind is a generalization of the standard C++ functions std::bind1st and std::bind2nd. It supports arbitrary function objects, functions, function pointers, and member function pointers, and is able to bind any argument to a specific value or route input arguments into arbitrary positions. bind does not place any requirements on the function object; in particular, it does not need the result_type, first_argument_type and second_argument_type standard typedefs.

boost::bind was proposed for standardization and a version of it was included in as std::tr1::bind and an improved version is included in the standard as std::bind (see ).
