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

NAME         top

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

SYNOPSIS         top

       #include <unistd.h>

       int setup(void);

DESCRIPTION         top

       setup() is called once from within linux/init/main.c.  It calls initialization
       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         top

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

ERRORS         top

       EPERM  Always, for a user process.

VERSIONS         top

       Since Linux 2.1.121, no such function exists anymore.

CONFORMING TO         top

       This function is Linux-specific, and should not be used in programs intended
       to be portable, or indeed in any programs at all.

NOTES         top

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