SETUP(2) Linux Programmer's Manual SETUP(2)NAMEsetup - setup devices and file systems, mount root file system
SYNOPSIS
#include <unistd.h>
_syscall0(int, setup)
int setup(void);
DESCRIPTIONsetup() is called once from within linux/init/main.c. It calls ini‐
tialization 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 VALUEsetup() 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.
