Defined in header <system_error>
class system_error;		(desde C++11)

std::system_error es el tipo de la excepción lanzada por varias funciones de la biblioteca (por lo general las funciones que interactúan con las instalaciones del sistema operativo, por ejemplo, el constructor de std::thread), cuando la excepción se ha asociado a un std::error_code que debe ser reportado .

Ejemplo

#include <thread>
#include <iostream>
#include <system_error>
 
int main()
{
    try {
        std::thread().detach(); // attempt to detach a non-thread
    } catch(const std::system_error& e) {
        std::cout << "Caught system_error with code " << e.code() 
                  << " meaning " << e.what() << '\n';
    }
}

Output:

Caught system_error with code generic:22 meaning Invalid argument
