- CHROOT(2) Minix Programmer's 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.
- SEE ALSO
- chdir(2).
