What does the GetWindowLong(hwnd, 0) mean?

QUESTION

What does the GetWindowLong(hwnd, 0) mean?

Asked 2020-Aug-20 at 14:49

LRESULT WINAPI TextViewWndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    TextView* ptv = (TextView*)GetWindowLong(hwnd, 0);
    switch (msg)
    {
        case WM_NCCREATE:

        if ((ptv = new TextView(hwnd)) == nullptr)
            return FALSE;

        SetWindowLong(hwnd, 0, (LONG)ptv);
        return TRUE;
}

Per the GetWindowLong() documentation:

nIndex

Type: int

The zero-based offset to the value to be retrieved. Valid values are in the range zero through the number of bytes of extra window memory, minus four; for example, if you specified 12 or more bytes of extra memory, a value of 8 would be an index to the third 32-bit integer.

...

The following values are also available when the hWnd parameter identifies a dialog box.

DWL_MSGRESULT
0
Retrieves the return value of a message processed in the dialog box procedure.

The code in question is for a window that wraps a TextView object. The window is NOT a dialog box, and there is an InitTextView() function beint called that registers a WNDCLASSEX whose cbWndExtra field is set to sizeof(TextView*) when calling RegisterClassEx():
