* Name: __cxa_atexit
*
* Description:
* __cxa_atexit() registers a destructor function to be called by exit().
* On a call to exit(), the registered functions should be called with
* the single argument 'arg'. Destructor functions shall always be
* called in the reverse order to their registration (i.e. the most
* recently registered function shall be called first),
*
* If shared libraries were supported, the callbacks should be invoked
* when the shared library is unloaded as well.
*
* Reference:
* Linux base
