void set_exception_at_thread_exit( std::exception_ptr p ) ;
(since C++11)

Stores the exception pointer p

The operation behaves as though set_value, set_exception, set_value_at_thread_exit, and set_exception_at_thread_exit

An exception is thrown if there is no shared state or the shared state already stores a value or exception.

Calls to this function do not introduce data races with calls to get_future (therefore they need not synchronize with each other).

Parameters

p - exception pointer to store. The behavior is undefined if p is nullptr

Return value

(none)

Exceptions

std::future_error on the following conditions:

  • *this has no shared state. The error code is set to no_state.
