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, ...)
