CHROOT(2)							     CHROOT(2)

NAME
       chroot - change root directory

SYNOPSIS
       chroot(dirname)
       char *dirname;

DESCRIPTION
       Dirname	is the address of the pathname of a directory, terminated by a
       null byte.  Chroot causes this directory to become the root  directory,
       the starting point for path names beginning with ``/''.

       In  order  for  a directory to become the root directory a process must
       have execute (search) access to the directory.

       This call is restricted to the super-user.

RETURN VALUE
       Upon successful completion, a value of 0	 is  returned.	 Otherwise,  a
       value of -1 is returned and errno is set to indicate an error.

ERRORS
       Chroot  will  fail  and	the root directory will be unchanged if one or
       more of the following are true:

       [ENOTDIR]      A component of the path name is not a directory.

       [EINVAL]	      The pathname contains a character	 with  the  high-order
		      bit set.

       [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an
		      entire path name exceeded 1023 characters.

       [ENOENT]	      The named directory does not exist.

       [EACCES]	      Search permission is denied for  any  component  of  the
		      path name.

       [ELOOP]	      Too  many symbolic links were encountered in translating
		      the pathname.

       [EFAULT]	      Path points  outside  the	 process's  allocated  address
		      space.

       [EIO]	      An  I/O  error occurred while reading from or writing to
		      the file system.
