std::promise
Member functions promise::promise promise::~promise promise::operator= promise::swap Getting the result promise::get_future Setting the result promise::set_value promise::set_value_at_thread_exit promise::set_exception promise::set_exception_at_thread_exit

Defined in header <future>
template< class T > class promise;	(1)	(since C++11)
template< class T > class promise<T&>;	(2)	(since C++11)
template<>          class promise<void>;	(3)	(since C++11)

The class template std::promise provides a facility to store a value that is later acquired asynchronously via a std::future object, that the std::promise can supply.

[edit] Member functions

(constructor)	constructs the promise object (public member function)
(destructor)	destructs the promise object (public member function)
operator=	moves the promise object (public member function)
swap	swaps two promise objects (public member function)
Getting the result
get_future	returns a future associated with the promised result (public member function)
Setting the result
set_value	sets the result to specific value (public member function)
set_value_at_thread_exit	sets the result to specific value while delivering the notification only at thread exit (public member function)
set_exception	sets the result to indicate an exception (public member function)
set_exception_at_thread_exit	sets the result to indicate an exception while delivering the notification only at thread exit (public member function)

[edit] Helper classes

std::uses_allocator<std::promise> (C++11)	specializes the std::uses_allocator type trait (class template specialization)
