NAME

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 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.
STANDARDS
Linux.
VERSIONS
Removed in Linux 2.1.121.
The calling sequence varied: at some times setup() has had a single ar-
gument void *BIOS and at other times a single argument int magic.
