NAME¶
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.
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.
