SETUP(2) Linux Programmer's 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 initial-
ization functions for devices and file systems configured into the ker-
nel and then mounts the root file system.
No user process may call setup. Any user process, even a process with
super-user 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 parameter void * BIOS and at other times a single
parameter int magic.
