std::_Exit
| Defined in header <cstdlib>
|
||
| [[noreturn]] void _Exit( int exit_code ) noexcept; |
(since C++11) | |
Causes normal program termination to occur without completely cleaning the resources.
Destructors of variables with automatic, thread local and static storage durations are not called. Functions passed to std::at_quick_exit() or std::atexit() are not called. Whether open resources such as files are closed is implementation defined.
If exit_code is 0 or EXIT_SUCCESS, an implementation-defined status indicating successful termination is returned to the host environment. If exit_code is EXIT_FAILURE, an implementation-defined status, indicating unsuccessful termination, is returned. In other cases implementation-defined status value is returned.

[edit] Notes
Although _Exit is required to be freestanding since C++23, it is not required to be available in a freestanding C implementation.
