DESCRIPTION

16       setup()  is  called  once from within linux/init/main.c.  It calls ini‐

18       kernel and then mounts the root file system.

21       with superuser permission, will receive EPERM.
22

RETURN VALUE

CONFORMING TO

30       This function is Linux specific, and should not  be  used  in  programs
31       intended to be portable, or indeed in any programs at all.  Since Linux
32       2.1.121, no such function exists anymore.  The calling sequence varied:
33       it  has  had a single parameter void * BIOS and at other times a single
34       parameter int magic.
