                                                                                          explain_link_or_die(3)

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

       This function is intended to be used in a fashion similar to the following example:
              explain_link_or_die(oldpath, newpath);

       oldpath The oldpath, exactly as to be passed to the link(2) system call.

       newpath The newpath, exactly as to be passed to the link(2) system call.

       Returns:
               This function only returns on success.  On failure, prints an explanation and exits.
