PROLOG         top

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

NAME         top

       sched_rr_get_interval — get execution time limits (REALTIME)

SYNOPSIS         top

       #include <sched.h>

       int sched_rr_get_interval(pid_t pid, struct timespec *interval);

DESCRIPTION         top

       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         top

       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         top

       The sched_rr_get_interval() function shall fail if:

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