Bug #: 30556
           Summary: user32 does not export Get/SetWindowLongPtr
           Product: Wine
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Created attachment 39968
  --> http://bugs.winehq.org/attachment.cgi?id=39968
python script that fails to access the functions

user32 does not export Get/SetWindowLongPtr on wine 32 bit

the following functions are not exported by user32.dll

GetWindowLongPtrA
SetWindowLongPtrA
GetWindowLongPtrW
SetWindowLongPtrW

just took a peek into dlls/user32/user32.spec where these functions are tagged
with "-arch=win64". guessing that this is the reason. if so, no idea if this is
by intention or not.

Hello,

this is by design = exactly what Windows does.

See MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms633585%28v=vs.85%2...

--- quote ---
To write code that is compatible with both 32-bit and 64-bit versions of
Windows, use GetWindowLongPtr. When compiling for 32-bit Windows,
GetWindowLongPtr is defined as a call to the GetWindowLong function.
--- quote ---

"defined as a call" means it is mapped to GetWindowLongA/W at compile time
(header file -> preprocessor).
See comment from "paulbassett13" (8/15/2010).

Wine source:
http://source.winehq.org/git/wine.git/blob/4180054c2fcd9b0fca0f3ef32c75af50d...

--- snip ----
3638 #ifdef _WIN64
3639 WINUSERAPI LONG_PTR    WINAPI GetWindowLongPtrA(HWND,INT);
3640 WINUSERAPI LONG_PTR    WINAPI GetWindowLongPtrW(HWND,INT);
