18 Language support library [language.support]

18.8 Exception handling [support.exception]

18.8.3 Abnormal termination [exception.terminate] terminate [terminate]

[[noreturn]] void terminate() noexcept;

Remarks: Called by the implementation when exception handling must be abandoned for any of several reasons ([except.terminate]), in effect immediately after throwing the exception. May also be called directly by the program.

Effects: Calls the current terminate_handler function. [ Note: A default terminate_handler is always considered a callable handler in this context.  — end note ]
