NAME
setup - setup devices and filesystems, mount root filesystemSYNOPSIS
#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 filesys‐ tem. No user process may call setup(). Any user process, even a process with superuser permis‐ sion, 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.CONFORMING TO
This function is Linux-specific, and should not be used in programs intended to be porta‐ ble, 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.COLOPHON
