function family The header <boost/function.hpp> defines the primary entry point to the function object wrappers, the class template boost::function. This class template is essentially a thin wrapper around a set of similar numbered function object wrappers, boost::function0, boost::function1, etc., where the number indicates the number of arguments passed to the function object target. The declaration of f above could also be written as:
