virtual ~ios_base();
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.
