#include <unistd.h> [[deprecated]] int setup(void);
LIBRARY
Standard C library (libc, -lc)
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.
