CHROOT(2)                     System Calls Manual                    CHROOT(2)

NAME
       chroot - change root directory

SYNOPSIS
       #include <unistd.h>

       int chroot(const 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.

       [ENAMETOOLONG] The path name exceeds PATH_MAX 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.  (Minix-vmd)

       [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.
