Defined in header <cstdlib>
[[noreturn]] void exit( int exit_code );		(since C++11)
void exit( int exit_code );		(until C++11)

Causes normal program termination to occur.

Several cleanup steps are performed:

• destructors of objects with thread local storage duration are called
• destructors of objects with static storage duration are called
• functions passed to std::atexit are called. If an exception tries to propagate out of any of the function, std::terminate is called
• all C streams are flushed and closed
• files created by std::tmpfile are removed
• control is returned to the host environment. If exit_code is EXIT_SUCCESS, an implementation-defined status, indicating successful termination is returned. If exit_code is EXIT_FAILURE, an implementation-defined status, indicating unsuccessful termination is returned. In other cases implementation-defined status value is returned.

Destructors of variables with automatic storage durations are not called.

Parameters

exit_code

-

exit status of the program

Return value

(none)
