sched_getparam(3RT)					    Realtime Library Functions					       sched_getparam(3RT)

NAME
       sched_getparam - get scheduling parameters

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

       int sched_getparam(pid_t pid, struct sched_param *param);

DESCRIPTION
       The  sched_getparam()  function	returns the scheduling parameters of a process specified by pid in the sched_param structure pointed to by
       param.

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

       If  pid is 0, the scheduling parameters for the calling process will be returned. The behavior of the sched_getparam() function is unspeci-
       fied if the value of pid is negative.

RETURN VALUES
       Upon successful completion, the sched_getparam() function returns 0. If the call to sched_getparam() is unsuccessful, the function  returns
       -1 and sets errno to indicate the error.

ERRORS
       The  sched_getparam() function will fail if:

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

       EPERM	       The requesting process does not have permission to obtain the scheduling parameters of the specified process.

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

       ENOSYS.
