NAME

6       sched_getscheduler - get scheduling policy (REALTIME)
7

SYNOPSIS

9       #include <sched.h>
10
11       int sched_getscheduler(pid_t pid);
12
13

DESCRIPTION

15       The sched_getscheduler() function shall return the scheduling policy of
16       the process specified by pid. If the value  of  pid  is  negative,  the
17       behavior of the sched_getscheduler() function is unspecified.
18
19       The  values that can be returned by sched_getscheduler() are defined in
20       the <sched.h> header.
21
22       If a process specified by pid exists, and if the  calling  process  has
23       permission,  the  scheduling  policy  shall be returned for the process
24       whose process ID is equal to pid.
25
26       If pid is zero, the scheduling policy shall be returned for the calling
27       process.
28

RETURN VALUE

30       Upon  successful  completion,  the  sched_getscheduler() function shall
31       return the scheduling policy of the specified process. If unsuccessful,
32       the function shall return -1 and set errno to indicate the error.
33

ERRORS

35       The sched_getscheduler() function shall fail if:
36
37       EPERM  The requesting process does not have permission to determine the
38              scheduling policy of the specified process.
39
40       ESRCH  No process can be found corresponding to that specified by pid.
