 (since C++11)

Constructs an std::error_code object from a value of type std::io_errc as if by return std::error_code(static_cast<int>(e), std::iostream_category()). This function is called by the constructor of std::error_code when given an std::io_errc argument.

Parameters

e - error code number

Return value

A value of type std::error_code 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>
int main()
{
    std::error_code ec = std::make_error_code(std::io_errc::stream);
    std::cout << "Error code from io_errc::stream has category "
              << ec.category().name() << '\n';
}

Output: 

Error code from io_errc::stream has category iostream
