template<     class Arg1,     class Arg2,     class Result > class pointer_to_binary_function : public std::binary_function<Arg1, Arg2, Result>;		(deprecated)

std::pointer_to_binary_function is a function object that acts as a wrapper around a binary function.

Member functions

(constructor)	constructs a new pointer_to_binary_function object with the supplied function (public member function)
operator()	calls the stored function (public member function)

std::pointer_to_binary_function::pointer_to_binary_function

explicit pointer_to_binary_function( Result (*f)(Arg1,Arg2) );

Constructs a pointer_to_binary_function function object with the stored function f.

Parameters

f

-

pointer to a function to store

std::pointer_to_binary_function::operator()

Result operator()( Arg1 x1, Arg2 x2 ) const;

Calls the stored function.

Parameters

x1, x2

-

arguments to pass to the function

Return value

The value returned by the called function.
