sched_getscheduler(3C)					   Standard C Library Functions 				    sched_getscheduler(3C)

NAME

       sched_getscheduler - get scheduling policy

SYNOPSIS

       #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(3C)
       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:

       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.
