SYNOPSIS
#include <sched.h>
int sched_rr_get_interval(pid_t pid,
struct timespec *interval);
DESCRIPTION
The sched_rr_get_interval() function updates the timespec structure
referenced by the interval argument to contain the current execution
time limit (that is, time quantum) for the process specified by pid. If
pid is 0, the current execution time limit for the calling process will
be returned.
RETURN VALUES
If successful, the sched_rr_get_interval() function returns 0. Other‐
wise, it returns −1 and sets errno to indicate the error.
ERRORS
The sched_rr_get_interval() function will fail if:
