       chroot() - change root directory

       causes  the  named directory to become the root directory, the starting
       point for path searches for path names beginning with path points to  a
       path  name  naming  a directory.	 The user's working directory is unaf‐
       fected by the system call.

       The entry in the root directory is interpreted to mean the root	direc‐
       tory  itself.  Thus, cannot be used to access files outside the subtree
       rooted at the root directory.

   Security Restrictions
       The effective user ID of the process must be a user with the  privilege
       to  change  the	root directory.	 system call should be called within a
       single threaded process.	 A process should invoke  system  call	before
       the  system call to change the current working directory of the process
       to the new root directory.

       See privileges(5) for more information about privileged access on  sys‐
       tems that support fine-grained privileges.

       returns the following values:

	      Successful completion.
		     is set to indicate the error.

       fails  and  the	root directory remains unchanged if one or more of the
       following is true:

	      Any component of the path name is not a directory.

	      The named directory does not exist or a component of the
			     path does not exist.

	      The effective user
			     ID is not a user who has the privilege.

	      path	     points outside the allocated address space of the
			     process.  The reliable detection of this error is
			     implementation dependent.

	      The length of the specified path name exceeds
			     bytes, or the length of a component of  the  path
			     name exceeds bytes while is in effect.

	      Too many symbolic links were encountered in translating the path
