bad_alloc
needs to be constructible without allocating memory, which is why its constructor does not take a message parameter. You can of course subclass it and override what
.
How to throw std::bad_alloc with a custom message in C++?
質問
Since VS2008 the class bad_alloc does not provide a constructor with string parameter. Is there any possibility to create a custom message without overwriting the class like this?
// this is only pseudo-code
class custom_exception : bad_alloc {
public:
string Message;
custom_exception(string m) {Message = m;}
}
