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

for setting  unique names for a threads.

See the Linux manpage :

 

https://linux.die.net/man/3/pthread_setname_np

 

 

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

 

https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/apis/pthread_setname_np.htm

 

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
