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



NAME
       setup - setup devices and file systems, mount root file system

SYNOPSIS
       #include <&lt;unistd.h>&gt;

       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.

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.  Since Linux
       2.1.121, no such function exists anymore.  The calling sequence varied:
       it  has  had  a  single argument void *BIOS and at other times a single
       argument int magic.

COLOPHON
