Member functions

packaged_task::packaged_task

packaged_task::~packaged_task

packaged_task::operator=

packaged_task::valid

packaged_task::swap

Getting the result

packaged_task::get_future

Execution

packaged_task::operator()

packaged_task::make_ready_at_thread_exit

packaged_task::reset

 

~packaged_task();

Abandons the shared state and destroys the stored task object.

As with std::promise::~promise, if the shared state is abandoned before it was made ready, an std::future_error exception is stored with the error code std::future_errc::broken_promise).

Parameters

(none)
