Standard C Library Functions               sched_getscheduler(3C)



NAME
     sched_getscheduler - get scheduling policy

SYNOPSIS
     #include 

     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()  func-
     tion is unspecified.


     The values that can be returned by sched_getscheduler()  are
     defined  in  the  header    and  described  on  the
     sched_setscheduler(3C) manual page.


     If a process specified by pid exists and if the calling pro-
     cess  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()  func-
     tion 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:

     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.
