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.
