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 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
       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.
