[Bug 18772] New: Missing User32.PrintWindow implementation

http://bugs.winehq.org/show_bug.cgi?id=18772

Summary: Missing User32.PrintWindow implementation
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

There's a missing function in user32.dll : PrintWindow. It cause crash for an
application:
wine: Call from 0x7bc486d0 to unimplemented function USER32.dll.PrintWindow,
aborting

The specification of the function could be found here:
http://msdn.microsoft.com/en-us/library/dd162869.aspx

BOOL PrintWindow(
    HWND hwnd,
    HDC hdcBlt,
    UINT nFlags
);

It appears that a simple redirection to WM_PRINT SendMessage could work, i.e.
(not tested):

BOOL WINAPI PrintWindow( HWND sourceHandle, HDC destinationHandle, UINT nFlags)
{
    return (SendMessageA(sourceHandle, WM_PRINT, (WPARAM)destinationHandle, 
PRF_CHILDREN | PRF_CLIENT | PRF_ERASEBKGND | PRF_NONCLIENT | PRF_OWNED));
}

I've tried to test this function by adding it to painting.c, but the program
keeps complain about missing function, don't understand why

Regards
