From cppreference.com
< cpp‎ | utility‎ | functional

template< class F, class T > std::binder1st<F> bind1st( const F& f, const T& x ); | (1) | (deprecated)
template< class F, class T > std::binder2nd<F> bind2nd( const F& f, const T& x ); | (2) | (deprecated)

Binds a given argument `x` to a first or second parameter of the given binary function object `f`. That is, stores `x` within the resulting wrapper, which, if called, passes `x` as the first or the second parameter of `f`.

1) Binds the first argument of `f` to `x`. Effectively calls std::binder1st<F>(f, typename F::first_argument_type(x)).

2) Binds the second argument of `f` to `x`. Effectively calls std::binder2nd<F>(f, typename F::second_argument_type(x)).

### [edit] Parameters

f | - | pointer to a function to bind an argument to
x | - | argument to bind to `f`

### [edit] Return value

A function object wrapping `f` and `x`.

### [edit] Exceptions
