It should be possible, but I haven't yet seen a reason to write it.
One thing that concerns me is that IBM restricted the use of raw sockets
starting with V4R4.  Hopefully a ping application wouldn't need to cross
the line where they've decided to restrict you, but I don't know for sure.

You need it for Pthread?!  But RPG does not support threads!!
If you're running the RPG procedure in a serialized manner, you may as
well just call the command...

Maybe you should hire a C programmer to help you?  C will work with
threads, and it would make porting the application a lot easier.  You
might even be able to find ping sources that are released with a BSD or
GPL license that you can simply compile on your iSeries and be done with
it...
