NAME

6       sched_getparam - get scheduling parameters (REALTIME)
7

SYNOPSIS

9       #include <sched.h>
10
11       int sched_getparam(pid_t pid, struct sched_param *param);
12
13

DESCRIPTION

15       The sched_getparam() function shall return the scheduling parameters of
16       a process specified by pid in the sched_param structure pointed  to  by
17       param.
18
19       If  a  process  specified by pid exists, and if the calling process has
20       permission, the scheduling parameters for the process whose process  ID
21       is equal to pid shall be returned.
22
23       If pid is zero, the scheduling parameters for the calling process shall
24       be returned. The behavior of the sched_getparam() function is  unspeci‐
25       fied if the value of pid is negative.
26

RETURN VALUE

28       Upon  successful completion, the sched_getparam() function shall return
29       zero. If the call to sched_getparam()  is  unsuccessful,  the  function
30       shall return a value of -1 and set errno to indicate the error.
31

ERRORS

33       The sched_getparam() function shall fail if:
34
35       EPERM  The  requesting  process  does not have permission to obtain the
36              scheduling parameters of the specified process.
37
38       ESRCH  No process can be found corresponding to that specified by pid.
