NAME

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

 

SYNOPSIS

       #include

 

       _syscall0(int, setup);

 

       int setup(void);

 

DESCRIPTION

       setup is called once from within linux/init/main.c.  It calls initial-

       ization 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

       super-user permission, will receive EPERM.

 

RETURN VALUE

       setup always returns -1 for a user process.

 

ERRORS

       EPERM  Always, for a user process.

 

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.  Since

       Linux 2.1.121, no such function exists anymore.  The calling  sequence

       varied: it has had a single parameter void * BIOS and at other times a

       single parameter int magic.
