       Destroys the
       
        ios_base
       
       object.
      
Before any of the member functions would yield undefined results, calls callbacks, registered by register_callback() passing erase_event as parameter. Then, deallocates any memory obtained.
       No operations on
       
        rdbuf
       
       are performed, it is not destroyed.
