NAME

       setup - setup devices and filesystems, mount root filesystem

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <unistd.h>

       [[deprecated]] int setup(void);

DESCRIPTION

       setup()  is  called once from within linux/init/main.c.  It calls initialization functions
       for devices  and  filesystems  configured  into  the  kernel  and  then  mounts  the  root
       filesystem.

       No  user  process  may  call  setup().   Any  user  process, even a process with superuser
       permission, will receive EPERM.

RETURN VALUE

       setup() always returns -1 for a user process.

ERRORS

       EPERM  Always, for a user process.

STANDARDS

       Linux.

VERSIONS

       Removed in Linux 2.1.121.

       The calling sequence varied: at some times setup() has had a  single  argument  void *BIOS
       and at other times a single argument int magic.
