GUI app and winAPI calls

[aurel]

I looked into mingW compiler include - winuser and there is structure declared:

typedef struct tagWNDCLASSEXA {
    UINT cbSize;
    UINT style;
    WNDPROC lpfnWndProc;
    int cbClsExtra;
    int cbWndExtra;
    HINSTANCE hInstance;
    HICON hIcon;
    HCURSOR hCursor;
    HBRUSH hbrBackground;
    LPCSTR lpszMenuName;
    LPCSTR lpszClassName;
    HICON hIconSm;
  } WNDCLASSEXA,*PWNDCLASSEXA,*NPWNDCLASSEXA,*LPWNDCLASSEXA;


which is what i expected ...so it is already there
then i need to look into QB64 source and check what is there declared and how ,
and i think that only old structure is used

which is this one :
typedef struct tagWNDCLASSA {
    UINT style;
    WNDPROC lpfnWndProc;
    int cbClsExtra;
    int cbWndExtra;
    HINSTANCE hInstance;
    HICON hIcon;
    HCURSOR hCursor;
    HBRUSH hbrBackground;
    LPCSTR lpszMenuName;
    LPCSTR lpszClassName;
  } WNDCLASSA,*PWNDCLASSA,*NPWNDCLASSA,*LPWNDCLASSA;
