setup()
is called once from within
linux/init/main.c.
It calls initialization 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 VALUE
setup()
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 argument
void *BIOS
and at other times a single argument
int magic.
