Defined in header <system_error>
std::error_condition make_error_condition( std::errc e );		(since C++11)

Creates an error condition for an errc value e. Sets the error code to int(e) and error category to std::generic_category.

Parameters

e

-

standard error code

Return value

Error condition for e.

Exceptions

noexcept specification:  

noexcept

  

Example

Run this code

#include <system_error>
#include <string>
#include <iostream>
 
int main()
{
    auto err = std::make_error_condition(std::errc::invalid_argument);
    std::cout << err.message() << '\n';
}

Possible output:

Invalid argument
