Dear threading folk: This afternoon I wrote some threaded code for Mac OS X, and then checked it out on FreeBSD and was a bit surprised when it compiled but didn't work. Turns out, of course, that on Mac OS X I'd omitted -lpthread and not noticed, as the thread primitives are in libSystem. It ran, and the reason I ran into trouble is that, although no-op locking calls are fine, getting back "success" from pthread_key_create() when it has actually failed is problematic. Would it be possible to make the thread stub for pthread_key_create() return an error, instead of succeeding (but not actually succeeding)? Or, perhaps better yet, I should get a link-time error for that function, even though I shouldn't get one for lock/unlock? Thanks, Robert N M Watson Computer Laboratory University of Cambridge
