A nested function must not be called after the containing function exits. A nested function cannot use a goto statement to jump to a label in the containing function, or to a local label declared with the __label__ keyword inherited from the containing function.Parent...
Ifnested_ptr()returns a null pointer, the function callsstd::terminate(). Otherwise, it throws the stored exception captured by*this. Requirements Header:<exception> Namespace:std See also exception Class Thread Safety in the C++ Standard Library ...
In the preceding example, thequalified-type-namesyntax is used to declare the function name. The declaration: C++ BufferedIO::BufferedInput::read() means "thereadfunction that is a member of theBufferedInputclass that is in the scope of theBufferedIOclass." Because this declaration uses thequalif...
