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.

Parameters

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

Return value

os
