SETUP(2) Linux Programmers Manual SETUP(2)
setup - setup devices and file systems, mount root file system
setup() 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.
setup() always returns -1 for a user process.
EPERM Always, for a user process.
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 argument void *BIOS and at other times a single
argument int magic.
This page is part of release 3.05 of the Linux man-pages project. A
