exception::what

 

Defined in header <stdexcept>
class invalid_argument;

Defines a type of object to be thrown as exception. It reports errors that arise because an argument value has not been accepted.

This exception is thrown by std::bitset::bitset, and the std::stoi and std::stof families of functions.

Inheritance diagram

Member functions

(constructor)

constructs the exception object (public member function)

std::invalid_argument::invalid_argument

explicit invalid_argument( const std::string& what_arg );	(1)
explicit invalid_argument( const char* what_arg );	(2)	(since C++11)

Constructs the exception object with what_arg as explanatory string that can be accessed through what().

Parameters

what_arg

-

explanatory string

Exceptions

(none)

Inherited from std::exception

Member functions

(destructor) [virtual]	destructs the exception object (virtual public member function of std::exception)
what [virtual]	returns an explanatory string (virtual public member function of std::exception)

Notes

The purpose of this exception type is similar to the error condition std::errc::invalid_argument (thrown in std::system_error from member functions of std::thread) and the related errno constant EINVAL.
