NAME

sched_rr_get_interval — get execution time limits ( REALTIME)

SYNOPSIS

#include <sched.h>
int sched_rr_get_interval(pid_t pid, struct timespec *interval);

DESCRIPTION

The sched_rr_get_interval() function shall update 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 zero, the current execution time limit for the calling process shall be returned.

RETURN VALUE

If successful, the sched_rr_get_interval() function shall return zero. Otherwise, it shall return a value of −1 and set errno to indicate the error.
