NAME

       setup - setup devices and filesystems, mount root filesystem

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <unistd.h>

       [[deprecated]] int setup(void);

DESCRIPTION

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

STANDARDS

       Linux.

VERSIONS

       Removed in Linux 2.1.121.

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