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 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.
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.
