PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME
       sched_getparam - get scheduling parameters (REALTIME)

SYNOPSIS
       #include <sched.h>

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

DESCRIPTION
       The sched_getparam() function shall return 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 shall be returned.

       If pid is zero, the scheduling parameters for the calling process shall be returned. The  behavior  of  the  sched_getparam()  function	is
       unspecified if the value of pid is negative.

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

ERRORS
       The sched_getparam() function shall fail if:

       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.
