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



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

SYNOPSIS
       #include <unistd.h>

       _syscall0(int, setup);

       int setup(void);

DESCRIPTION
       setup is called once from  within  linux/init/main.c.   It
       calls  initialization  functions for devices and file sys­
       tems configured into the kernel and then mounts  the  root
       file system.

       No  user process may call setup.  Any user process, even a
       process with super-user 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 pro­
       grams at all.   Since  Linux  2.1.121,  no  such  function
       exists anymore.  The calling sequence varied: it has had a
       single parameter void * BIOS and at other times  a  single
       parameter int magic.
