That is not, however, multi-thread safe nor advisable unless you clearly
indicate in the man page to the function that subsequent calls to the
function wipe out the result of previous calls. It's not even single
thread safe if you have more than one interface and don't know that
later calls wipe this buffer out. Best to avoid library routines such
as this.
