void set_exception_at_thread_exit( std::exception_ptr p ); | (since C++11) |
Stores the exception pointer p
into the shared state without making the state ready immediately. The state is made ready when the current thread exits, after all variables with thread-local storage duration have been destroyed.
The operation is atomic, i.e. it behaves as though they acquire a single mutex associated with the promise object while updating the promise object.
An exception is thrown if there is no shared state or the shared state already stores a value or exception.
Parameters
p | - | exception pointer to store |
Return value
(none).
Exceptions
std::future_error
on the following conditions:
-
*this
has no shared state. The error category is set tono_state
. - The shared state already stores a value or exception. The error category is set to
promise_already_satisfied
.
