                                                                                        explain_chroot_or_die(3)

       The  explain_chroot_or_die  function is used to call the chroot(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_chroot(3) function, and then the process  terminates
       by calling exit(EXIT_FAILURE).

       The explain_chroot_on_error function is used to call the chroot(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_chroot(3) function, but still returns to the caller.

       pathname
               The pathname, exactly as to be passed to the chroot(2) system call.

       The explain_chroot_or_die function is intended to be used in a fashion similar to the following example:
              explain_chroot_or_die(pathname);

       explain_chroot_or_die - change root directory and report errors

       The  explain_chroot_or_die  function  only  returns  on  success,  see chroot(2) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_chroot_on_error function always returns the value return  by  the  wrapped  chroot(2)  system
       call.

chroot(2)
               change root directory

       explain_chroot(3)
               explain chroot(2) errors

       exit(2) terminate the calling process

       #include <libexplain/chroot.h>
       void explain_chroot_or_die(const char *pathname);
       int explain_chroot_on_error(const char *pathname))
