#include <stdio.h>
#include <unistd.h>
#include <sched.h>

main()
{


  printf("Valid priority range for SCHED_OTHER: %d - %d\n",
  sched_get_priority_min(SCHED_OTHER),

  printf("Valid priority range for SCHED_FIFO: %d - %d\n",

  printf("Valid priority range for SCHED_RR: %d - %d\n",
  sched_get_priority_min(SCHED_RR),
  sched_get_priority_max(SCHED_RR));
}

Output

Valid priority range for SCHED_OTHER: 0 - 0

Valid priority range for SCHED_FIFO: 1 - 99

Valid priority range for SCHED_RR: 1 - 99
