@subsection Priority
In the RTEMS implementation of the POSIX API, the priorities range from
the low priority of sched_get_priority_min() to the highest priority of
sched_get_priority_max(). Numerically higher values represent higher
the low priority of @code{sched_get_priority_min()} to the highest priority of
@code{sched_get_priority_max()}. Numerically higher values represent higher
