std::error_condition make_error_condition( std::io_errc e );
 (since C++11)

Constructs an std::error_condition object from a value of type std::io_errc as if by return std::error_condition(static_cast<int>(e), std::iostream_category()).

Parameters

e - error code number

Return value

A value of type std::error_condition that holds the error code number from e associated with the error category "iostream".

Exceptions

noexcept specification:  
noexcept
  

Example

Run this code
#include <iostream>
#include <system_error>
#include <string>
 
int main()
{
    std::error_condition ec  = std::make_error_condition(std::io_errc::stream);
    std::cout << "error condition for io_errc::stream has value " << ec.value()
              << "\nand message \"" << ec.message() << "\"\n";
}

Output: 

error condition for io_errc::stream has value 1
and message "unspecified iostream_category error"
