Functions


template<typename _Res , typename... _Args> bool std::operator!= (const function< _Res(_Args...)> &__f, nullptr_t) noexcept
Compares a polymorphic function object wrapper against 0 (the NULL pointer). template<typename _Res , typename... _Args> bool std::operator!= (nullptr_t, const function< _Res(_Args...)> &__f) noexcept
template<typename _Res , typename... _Args> bool std::operator== (const function< _Res(_Args...)> &__f, nullptr_t) noexcept
Compares a polymorphic function object wrapper against 0 (the NULL pointer). template<typename _Res , typename... _Args> bool std::operator== (nullptr_t, const function< _Res(_Args...)> &__f) noexcept
template<typename _Res , typename... _Args> void std::swap (function< _Res(_Args...)> &__x, function< _Res(_Args...)> &__y) noexcept
Swap the targets of two polymorphic function object wrappers.
