chroot

【文法】

chroot ファイル名


【説明】

This function works like the system call by the same name: it makes the named 
directory the new root directory for all further pathnames that begin with a `/'
 by your process and all its children.  (It doesn't change your current working 
directory, which is unaffected.)  For security reasons, this call is restricted 
to the superuser. If FILENAME is omitted, does a `chroot' to `$_'.
