SETUP(2)                   Linux Programmer's Manual                  SETUP(2)

NAME
       setup - setup devices and file systems, mount root file system
SYNOPSIS
       #include <unistd.h>
       int setup(void);
DESCRIPTION
       setup()  is  called  once from within linux/init/main.c.  It calls ini-
       tialization functions for devices and file systems configured into  the
       kernel and then mounts the root file system.
       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.
VERSIONS
       Since Linux 2.1.121, no such function exists anymore.
CONFORMING TO
       This function is Linux-specific, and should not  be  used  in  programs
       intended to be portable, or indeed in any programs at all.
NOTES
       The  calling  sequence  varied: at some times setup () has had a single
       argument void *BIOS and at other times a single argument int magic.
