std::make_error_condition(std::io_errc): std::make_error_condition(std::io_errc)

NAME

std::make_error_condition(std::io_errc) - std::make_error_condition(std::io_errc)

Synopsis


Defined in header <ios>
std::error_condition make_error_condition( std::io_errc e ) noexcept; (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".

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"
