domain_error Class
The class serves as the base class for all exceptions thrown to report a domain error (as in mathematics, not networking).
Syntax
class domain_error : public logic_error {
public:
explicit domain_error(const string& message);
explicit domain_error(const char *message);
};
Remarks
The value returned by what() is a copy of message.data(). For more information, see what and data.
domain_error isn't thrown by any functions in the Microsoft implementation of the C++ Standard Library, but it might be thrown by third-party libraries or user code.
Example
// domain_error.cpp
// compile with: /EHsc
#include <exception>
#include <iostream>
#include <stdexcept>
#include <typeinfo>
using namespace std;
int main()
{
try
{
throw domain_error("Your domain is in error!");
}
catch (const exception& e)
{
cerr << "Caught: " << e.what() << endl;
cerr << "Type: " << typeid(e).name() << endl;
}
}
/* Output:
Caught: Your domain is in error!
Type: class std::domain_error
*/
