PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

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  execu-
       tion  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.

ERRORS
       The sched_rr_get_interval() function shall fail if:

       ESRCH  No process can be found corresponding to that specified by pid.
