CreateDialogIndirectParam function Null safety user32

int CreateDialogIndirectParam(
  1. int hInstance,
  2. Pointer<DLGTEMPLATE> lpTemplate,
  3. int hWndParent,
  4. Pointer<NativeFunction<DlgProc>> lpDialogFunc,
  5. int dwInitParam
)

Creates a modeless dialog box from a dialog box template in memory. Before displaying the dialog box, the function passes an application-defined value to the dialog box procedure as the lParam parameter of the WM_INITDIALOG message. An application can use this value to initialize dialog box controls.
