PROLOG
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
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 struc-
ture 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.
The following sections are informative.
