Elemento definito nell'header <ios>
std::error_code make_error_code(std::io_errc e );		(dal C++11)

Costruisce un oggetto std::error_code da un valore di tipo std::io_errc come per returnstd::error_code(static_cast<int>(e), std::iostream_category()). Questa funzione viene chiamata dal costruttore di std::error_code quando somministrato un argomento std::io_errc.

Original:

Constructs an std::error_code object from a value of type std::io_errc as if by returnstd::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.
