Hi Matthias, I dont think it exists on AIX: We use it to set the thread name for debugging support (see os::set_native_thread_name). I personally think it is terribly important, since debugging on AIX in dbx is something we try to avoid :) Do you plan to commonize the implementation of os::set_native_thread_name for all Posix platforms? If yes, this makes sense, but I would dlsym the function. Cheers, Thomas On Thu, Oct 10, 2019 at 9:37 AM Baesken, Matthias <matthias.baesken@sap.com> wrote:
Hello, currently pthread_setname_np is used on e.g. Linux and BSD

for setting unique names for a threads.
See the Linux manpage :

I noticed that the function seems to be available now on IBM i

but I did not find it on AIX - are there plans to include it on AIX ? Or is it already available in some SP ?
If not is there a replacmenet function for it we could use ?
Thanks, Matthias
