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.
