sched_get_priority_min(int policy);
The sched_get_priority_max and sched_get_priority_min functions shall return the appropriate maximum or minimum, respectively, for the scheduling policy specified by policy.
The value of policy shall be one of the scheduling policy values defined in <sched.h>.
If successful, the sched_get_priority_max and sched_get_priority_min functions shall return the appropriate maximum or minimum values, respectively. If unsuccessful, they shall return a value of -1 and set errno to indicate the error.
The sched_get_priority_max and sched_get_priority_min functions shall fail if:
