sched_getscheduler(3RT) 				    Realtime Library Functions					   sched_getscheduler(3RT)

NAME
       sched_getscheduler - get scheduling policy

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

       int sched_getscheduler(pid_t pid);

DESCRIPTION
       The  sched_getscheduler()  function  returns  the  scheduling  policy of the process specified by pid. If the value of pid is negative, the
       behavior of the sched_getscheduler() function is unspecified.

       The values that can be returned by sched_getscheduler() are defined in the header <sched.h> and described  on  the  sched_setscheduler(3RT)
       manual page.

       If  a  process  specified  by  pid exists and if the calling process has permission, the scheduling policy will be returned for the process
       whose process ID is equal to pid.

       If pid is 0, the scheduling policy will be returned for the calling process.

RETURN VALUES
       Upon successful completion, the sched_getscheduler() function returns the scheduling policy of the specified process. If unsuccessful,  the
       function returns -1 and sets errno to indicate the error.

ERRORS
       The  sched_getscheduler() function will fail if:

       ENOSYS	       The sched_getscheduler() function is not supported by the system.

       EPERM	       The requesting process does not have permission to determine the scheduling policy of the specified process.

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

       ENOSYS.
