Date: Tue, 05 Jul 2005 21:43:26 +1000 From: Sean Childs Subject: [SDL] Compiling SDL 1.2.8 with the free Borland compiler When compiling SDL 1.2.8 with the free Borland compiler, I received this error (there is a similar error that occurs in src\video\windx5\sdl_dx5events.c): Error E2342 ..\..\src\video\windib\sdl_dibevents.c 189: Type mismatch in parameter 'lpPrevWndFunc' (wanted 'int (__stdcall *)()', got 'long (__stdcall *)(void *,unsigned int,unsigned int,long)') in function DIB_HandleMessage I checked the MSDN library at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/ windowsuserinterface/windowing/windowprocedures/windowprocedurereference/wind owprocedurefunctions/callwindowproc.asp and it had this to say: If STRICT is not defined, the lpPrevWndFunc parameter has the data type FARPROC. The FARPROC type is declared as follows: int (FAR WINAPI * FARPROC) () In C, the FARPROC declaration indicates a callback function that has an unspecified parameter list. In C++, however, the empty parameter list in the declaration indicates that a function has no parameters. This subtle distinction can break careless code. Following is one way to handle this situation: #ifdef STRICT WNDPROC MyWindowProcedure #else FARPROC MyWindowProcedure #endif ... lResult = CallWindowProc(MyWindowProcedure, ...)
