SETUP
NAME SYNOPSIS DESCRIPTION RETURN VALUE ERRORS CONFORMING TO
setup - setup devices and file systems, mount root file system
#include
_syscall0(int, setup);
int setup(void);
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 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.
