The_onexitfunction is passed the address of a function (function) to be called when the program terminates normally. Successive calls to_onexitcreate a register of functions that are executed in LIFO (last-in-first-out) order. The functions passed to_onexitcan't take parameters. ...

The C++ standard guarantees that functions registered with std::atexit are called in the reverse order of their registration, except that a function is called after any previously registered functions that had already been called at the time it was registered. As a consumer of the library, this...
