Defined in header <future>
std::error_code make_error_code( std::future_errc e );		(since C++11)

Constructs an std::error_code object from a value of type std::future_errc as if by:

std::error_code(static_cast<int>(e), std::future_category()).

This function is called by the constructor of std::error_code when given an std::future_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 "future".
