Hi,
the documentation refers to the Native Task Status (T_*) when it comes
to documenting rt_task_info.status. That is not correct. That field
contains far more flags than T_* is describing and, even worse, comes
with two collisions: T_PRIMARY and T_JOINABLE are not reported by
rt_task_inquire, rather T_RELAX (!T_PRIMARY, arrrg...) and T_HELD.
I see two ways out of this:
a) Redirect the documentation to the nucleus thread state flags.
b) Redefine the numerical values of T_PRIMARY and T_JOINABLE (the spare
bits are unused with the native skin), add missing but possibly
interesting flags as T_-constants and ensure that T_PRIMARY and
T_JOINABLE are correctly injected on rt_task_inquire from user
space.
Somehow I tend to prefer a)...
