sched_rr_get_interval(3RT)				    Realtime Library Functions					sched_rr_get_interval(3RT)

NAME
       sched_rr_get_interval - get execution time limits

SYNOPSIS
       cc [ flag... ] file... -lrt [ library... ]
       #include <sched.h>

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

DESCRIPTION
       The  sched_rr_get_interval()  function  updates 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 0, the current execution time limit for the calling  process
       will be returned.

RETURN VALUES
       If successful, the sched_rr_get_interval() function returns 0. Otherwise, it returns -1 and sets errno to indicate the error.

ERRORS
       The  sched_rr_get_interval() function will fail if:

       ENOSYS	       The  sched_get_priority_max(3RT),  sched_get_priority_min(3RT),	and sched_rr_get_interval() functions are not supported by
		       the system.

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

NOTES
       Solaris	2.6  was  the  first  release to support libposix4/librt. Prior to this release, this function always returned -1 and set errno to
       ENOSYS.
