Many times I have called getLastError() after a Win32 function call failed, but the returned error code was obscure and not satisfactory documented.
For example, I am calling hWnd=CreateWindow(...) and get hWnd==NULL. I call GetLastError() and get 6. In WINERROR.H, error 6 is 'ERROR_INVALID_HANDLE' with no good explanation. The VC++ help and MSDN don't explain what does
this error mean in CreateWindow().
My question: Is there a place or book where all the Win32 errors are fully documented? E.g., where I can find what is the exact meaning of ERROR_INVALID_HANDLE for CreateWindow()? (I need a better explanation than the laconic text "The handle is invalid").
