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"
