    copied!<p>I am using WSAGetLastError function to retrieve failure details when using getHostByName function. But the error code returned by the function is 0042124C is not available in the documentation. Am I receiving the error code in some other format or am I using the function in a faulty way?</p> <p>Thanks.</p> <p>PS.
