[C++] GetLastError()

[출처] http://www.winapi.co.kr/ApiBoard/content.php?table=tblqa&pk=13489

FormatMessage()라는 함수인데, GetLastError()로 얻은 에러 코드가
무슨 에러인지 알고 싶으면???

char buffer[128];
FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM, NULL, GetLastError(),
NULL, buffer, 128, NULL);
MessageBox(hWnd, buffer, "Error", MB_ICONHAND);
