Defined in header <cstdlib>
void exit( int exit_code );

Causes normal program termination to occur.

Several cleanup steps are performed:

• destructors of objects with thread local [cpp/language/storage duration | storage duration]] are called
• destructors of objects with static storage duration are called
• functions passed to atexit() are called. If an exception tries to propagate out of any of the function, 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.

Causes abnormal program termination unless SIGABRT is being caught by a signal handler passed to signal and the handler does not return.

Destructors of variables with automatic, thread local and static storage durations are not called. Functions, passed to atexit() are also not called. Whether open resources such as files are closed is implementation defined. Implementation defined status is returned to the host environment that indicates unsuccessful execution.
