Ok, I probe that ‘dummy’ - I guess you mean the src/generic/SDL_syscond.c
code. Anyway, I think SDL_syscond.c is put into src/thread/generic by
mistake, since it contains WINAPI calls like CreateSemaphoreCE() etc.
Furthermore, it’s not included in the VisualC project that comes with SDL
package. I think it should be put in src/thread/windows/ and included in
.vcproj, and there should by some stub implementation in generic/ for
SDL_Cond* interface instead - like it is made for SDL_CreateThread there:
/* src/generic/SDL_systhread.c */
int
SDL_SYS_CreateThread(SDL_Thread * thread, void *args)
{
SDL_SetError(“Threads are not supported on this platform”);
return (-1);
}
Note that I’m on SDL 1.3.0-5538.

Condition variables aren’t natively supported by Windows until Windows 7 (l
ink http://msdn.microsoft.com/en-us/library/ms682052(v=vs.85).aspx) and
emulation of them isn’t perfect for versions < 7; the topic is already well
researched (link http://www1.cse.wustl.edu/~schmidt/win32-cv-1.html). I
thought thread/generic/ had implementations of CVs using other primitives
and that they were available for Win32 (I seem to recall a friend of mine
using them on Win32 before). Are you sure those aren’t being compiled in?Patrick

Hello,
I’m planning to use SDL_Cond* API in my code, but for windows-based
platforms, its implementation is missing. I’ve already noticed this post
http://forums.libsdl.org/viewtopic.php?t=4445&start=0&postdays=0&postorder=asc&highlight=sdlcondsignalfrom 2009. Could the age of that post mean, that there will be no
implementation e.g. through CreateEvent, SetEvent, WaitForObject,… Windows
APIs in near future?

You have to use the ‘dummy’ condition code. While the win32 "event"
functions generally operate as a condition, they do not feature everything
expected and as such can’t be used without breaking old code.
SDL aims to support as many targets as possible, and it is difficult for
the developer using SDL to make two releases (one for >Win7, another for
<=Win7).
