Do not explicitly or implicitly call std::quick_exit(), std::abort(), or std::_Exit(). When the default terminate_handler is installed or the current terminate_handler responds by calling std::abort() or std::_Exit(), do not explicitly or implicitly call std::terminate(). Abnormal process termination is the typical vector for denial-of-service attacks.

The std::exit() function is more complex. The C++ Standard, [basic.start.main], paragraph 4, states:

Terminating the program without leaving the current block (e.g., by calling the function std::exit(int) (17.5)) does not destroy any objects with automatic storage duration (11.4.6). If std::exit is called to end a program during the destruction of an object with static or thread storage duration, the program has undefined behavior.

You may call It is acceptable to call a termination function that safely executes destructors and properly cleans up resources, such as std::exit() only in a program that has not yet initialized any objects with automatic storage duration.

The execution of a function registered with 'std::atexit()' or 'std::at_quick_exit()' should not exit via an exception
Never allow an exception to be thrown from a destructor, deallocation, and swap
Do not throw from within destructor
There should be at least one exception handler to catch all otherwise unhandled exceptions
An empty throw (throw;) shall only be used in the compound-statement of a catch handler
Exceptions shall be raised only after start-up and before termination of the program
Each exception explicitly thrown in the code shall have a handler of a compatible type in all call paths that could lead to that point
Where a function's declaration includes an exception-specification, the function shall only be capable of throwing exceptions of the indicated type(s)
Function called in global or namespace scope shall not throw unhandled exceptions
Always catch exceptions
Properly define exit handlers
The library functions 'abort()' , function from the 'stdlib.h' or 'cstdlib' library shall not be used
Avoid throwing exceptions from functions that are declared not to throw
The 'quick_exit()' and '_Exit()' functions from the 'stdlib.h' or 'cstdlib' library shall not be usedAvoid throwing exceptions from functions that are declared not to throw
