Hmmm, POSIX talks about priorities in the range of
min .. max,
where
min = sched_get_priority_min(alg)
max = sched_get_priority_max(alg)
max - min >= 32, if alg == SCHED_FIFO or alg == SCHED_RR
and alg being the the scheduling algorithm (like SCHED_FIFO, ...)
Under Linux (according to 'man sched_get_priority_min') the follwoing
ranges apply:
SCHED_FIFO : min = 1, max = 99
SCHED_RR : min = 1, max = 99
SCHED_OTHER : min = 0, max = 0
