NAME    [Toc]    [Back]

     sched_rr_get_interval - get round robin scheduling	interval

C SYNOPSIS    [Toc]    [Back]

     #include <sched.h>

     int sched_rr_get_interval (pid_t pid<b>, struct timespec *interval<b>)

DESCRIPTION    [Toc]    [Back]

     sched_rr_get_interval stores the round robin scheduling interval at
     address interval for the process named by pid. If pid is set to zero,
     then sched_rr_get_interval	obtains	the interval for the calling process.

     sched_rr_get_interval will	fail if	one or more of the following are true:

     [EFAULT]	    The	address	specified by interval is outside the range of
		    the	caller's address space.

     [EPERM]	    The	calling	process	attempted to obtain the	scheduling
		    interval of	an unrelated process and the caller does not
		    have the CAP_SCHED_MGT capability.

     [ESRCH]	    The	process	named by pid does not exist.

DIAGNOSTICS    [Toc]    [Back]

     Upon successful completion, a value of 0 is returned to the calling
     process. Otherwise, a value of -1 is returned and errno is	set to
     indicate the error.
