The functions sched_get_priority_max() and sched_get_priority_min() return the max and min priorities available for the scheduling policy in force (currently 99 and 1 for SCHED_RR). What method can be used to discover the max priority currently available to the current process, as controlled by /etc/security/limits.conf (or whatever controls it at the time of the inquiry)? In particular this is for the kernel 2.6.19-1.2895.fc6 running (naturally) under Fedora Core 6. Thanks - jon
