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

NAME

     setup - setup devices and filesystems, mount root filesystem

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 filesystems configured  into  the
     kernel and then mounts the root filesystem.

     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.
