Steve's Posix has not been ported to LXRT yet. So if you call pthread
you are using those of Linux not of RTAI.
It can but before ending it you must return to soft real time. An hard
real time task does not mind about Linux priority. Once you made a Linux
process hard real time Linux does not know of it anymore, from that
point you must control it with RTAI APIs.
So to know who you are use rt_whoami(), there is no APIs for changing
priority. We usually do it ourselves directly. It is a bad way, we'll
add a function for that in 1.4.
