Calls abort or a function you specify using set_terminate.

void terminate( void );  

The terminate function is used with C++ exception handling and is called in the following cases:

  • A matching catch handler cannot be found for a thrown C++ exception.

  • An exception is thrown by a destructor function during stack unwind.

  • The stack is corrupted after throwing an exception.

terminate calls abort by default. You can change this default by writing your own termination function and calling set_terminate with the name of your function as its argument. terminate calls the last function given as an argument to set_terminate. For more information, see Unhandled C++ Exceptions.

    catch( int )  
        cout << "Caught some integer exception.\n";  
    cout << "This should never print.\n";  
void term_func()  
    cout << "term_func() was called by terminate().\n";  
    // ... cleanup tasks performed here  
    // If this function does not exit, abort is called.  

term_func() was called by terminate().  

Not applicable. To call the standard C function, use PInvoke. For more information, see Platform Invoke Examples.
