~scope_success()noexcept(noexcept(std::declval<EF&>()())); | (library fundamentals TS v3) | |
Calls the exit function if the result ofstd::uncaught_exceptions() is less than or equal to the counter of uncaught exceptions (typically on normal exit) and thescope_success is active, then destroys the storedEF (if it is a function object) and any other non-static data members.
Throws any exception thrown by calling the exit function.
Whether the destructor is called on stack unwinding can be detected by the comparison of the result ofstd::uncaught_exceptions() and the counter of uncaught exceptions in thescope_success.
Unlike other classes or class template specializations in the C++ standard library and other C++ TR/TS's,scope_success's destructor is permitted to throw an exception.
makes thescope_success inactive(public member function)[edit] |
