Elemento definito nell'header <exception>

std::bad_exception è il tipo di eccezione generata dal runtime C + + nei seguenti casi:

Original:

1)

Se un eccezione specificazione dinamica viene violata e std::unexpected lancia o genera nuovamente un'eccezione che viola ancora la specifica eccezione, ma la specifica eccezione consente std::bad_exception, std::bad_exception viene gettato.

Original:

If a eccezione specificazione dinamica is violated and std::unexpected throws or rethrows an exception that still violates the exception specification, but the exception specification allows std::bad_exception, std::bad_exception is thrown.

2)

Se std::exception_ptr memorizza una copia della deroga catturato e se il costruttore di copia dell'oggetto eccezione catturato da current_exception genera un'eccezione, l'eccezione catturata è un'istanza di std::bad_exception.

Original:

If std::exception_ptr stores a copy of the caught exception and if the copy constructor of the exception object caught by current_exception throws an exception, the captured exception is an instance of std::bad_exception.

Esempio

#include <iostream>#include <exception>#include <stdexcept>   void my_unexp(){throw;}   void test()throw(std::bad_exception){throwstd::runtime_error("test");}   int main(){std::set_unexpected(my_unexp);try{ test();}catch(const std::bad_exception& e){std::cerr<<"Caught "<< e.what()<<'\n';}}

Output:

Caught std::bad_exception
