std::invalid_argument
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.

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().
Because copying std::invalid_argument is not permitted to throw exceptions, this message is typically stored internally as a separately-allocated reference-counted string. This is also why there is no constructor taking std::string&&: it would have to copy the content anyway.
Parameters
| what_arg | - | explanatory string |
Exceptions
May throw std::bad_alloc.
Inherited from std::exception
Member functions
|
[virtual] | destroys the exception object (virtual public member function of std::exception) |
|
[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.
