Uh, cygutils. I didn't know that. > do not understand how to use it. It is unrealted to what you're doing. It uses XSI semaphores which require a running cygserver process. See the User's Guide. Your example code is using POSIX sempahores. > >> I wrote an example that works on Jaunty on x86-64 but not on Cygwin: > >> http://www.izecksohn.com/pedro/c/semaphores/semaphores.tar.gz > > > > Works for me. > > The persistence of the semaphore also works for you? > > For me, using the unpatched version, (not the CVS version), the > persistence works some times only.
