std::operator<<(std::error_code)

Defined in header `<system_error>`
template< class CharT, class Traits > std::basic_ostream<CharT,Traits>& operator<<( basic_ostream<CharT,Traits>& os, const error_code& ec );		(since C++11)

Performs stream output operation on error code ec.

Equivalent to os << ec.category().name() << ’:’ << ec.value.

os	-	output stream to insert data to
ec	-	error code
