exception — Exception handling
The exception
header file defines several types and functions related to the
handling of exceptions.
namespace std {
class exception;
class bad_exception;
typedef void (*terminate_handler)();
typedef void (*unexpected_handler)();
terminate_handler
set_terminate(terminate_handler ph) throw();
unexpected_handler
set_unexpected(unexpected_handler ph) throw();
void terminate();
void unexpected();
bool uncaught_exception();
};
bad_exception
class bad_exception : public exception {
};
The class describes an exception that can be thrown from an unexpected handler. The value returned by what() is an implementation-defined C string. None of the member functions throw any exceptions.
exception
class exception {
public:
exception() throw();
exception(const exception& rhs) throw();
exception& operator=(const exception& rhs) throw();
virtual ~exception() throw();
virtual const char *what() const throw();
};
The class serves as the base class for all exceptions thrown by certain expressions and by the Standard C++ library. The C string value returned by what() is left unspecified by the default constructor, but may be defined by the constructors for certain derived classes as an implementation-defined C string. None of the member functions throw any exceptions.
terminate_handler
typedef void (*terminate_handler)();
The type describes a pointer to a function suitable for use as a terminate handler.
unexpected_handler
typedef void (*unexpected_handler)();
The type describes a pointer to a function suitable for use as an unexpected handler.
