SCHED_RR_GET_INTERVAL(3)   POSIX Programmer's Manual  SCHED_RR_GET_INTERVAL(3)



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

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.

ERRORS
       The sched__rr__get__interval() function shall fail if:

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