In the platform SDK's shlobj.h I find: HANDLE _SHAllocShared(LPCVOID pvData, DWORD dwSize, DWORD dwDestinationProcessId);
Notice the lack of a WINAPI and the leading underscore. So this would indicate a cdecl API. But in dlls/shell32/undocshell.h I see: HANDLE WINAPI SHAllocShared(LPVOID pv, ULONG cb, DWORD pid); This really looks like the same function, just without the underscore. Furthermore shell32.spec says: 520 stdcall SHAllocShared (long long long) So who's right? The platform SDK that says this is a cdecl function or Wine's headers? There's the same issue for SHFreeShared, SHLockShared and SHUnlockShared. -- Francois Gouget [EMAIL PROTECTED] http://fgouget.free.fr/ Linux: It is now safe to turn on your computer.
