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 direc- tory, 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.
