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.

       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.

NAME

       sched_get_priority_max, sched_get_priority_min - get scheduling parameter limits

SYNOPSIS

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

       int sched_get_priority_max(int policy);

       int sched_get_priority_min(int policy);

DESCRIPTION

       The sched_get_priority_max() and sched_get_priority_min() functions return the appropriate maximum or minimum, respectfully, for the sched-
       uling policy specified by policy.

       The value of policy is one of the scheduling policy values defined in <sched.h>.

RETURN VALUES

       If successful, the sched_get_priority_max() and sched_get_priority_min() functions  return  the	appropriate  maximum  or  minimum  values,
       respectively. If unsuccessful, they return -1 and set errno to indicate the error.

ERRORS

       The  sched_get_priority_max() and sched_get_priority_min() functions will fail if:

       EINVAL	       The value of the policy parameter does not represent a defined scheduling policy.

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