Re: [Oorexx-devel] sem_init warning messages.
Hello Rick The official answer fo macOS semaphores Is to use Grand Central Dispatch's dispatch_semaphore_t. If You google with dispatch_semaphore_t You will find quite a few examples Or … very dumb suggestion Since it seems that named semaphores are still supported Why not use under the covers a named semaphore with a dummy name As I said… it might be a dumb suggestion E > On 4 Dec 2018, at 22:21, Rick McGuire wrote: > > It appears that the sem_init deprecation warnings on the Mac are more than > just warnings.

[Oorexx-devel] sem_init warning messages.
It appears that the sem_init deprecation warnings on the Mac are more than just warnings. That function always returns an error on the Mac. Unfortunately, it would prove difficult to replace it with an alternative given how this function is currently constructed. I don't believe this function has ever worked on the Mac, and I doubt it is used very often, since it is fundamentally broken if you are trying to create an unnamed semaphore. No sure how to proceed with this. Rick ___ Oorexx-devel mailing list Oorexx-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oorexx-devel
