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
|
|

|
|
|
|
[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)
|
