       The  explain_fchdir_or_die  function  is  used  to  change  directory  via the fchdir(2) system call.  On
       failure, it prints an error message on stderr via explain_fchdir(3), and exits.

       This function is intended to be used in a fashion similar to the following example:
              explain_fchdir_or_die(fildes);

       fildes  exactly as to be passed to the fchdir(2) system call.

       explain_fchdir_or_die - change directory and report errors

fchdir(3)
               change working directory

       explain_fchdir(3)
               report fchdir(2) errors

       exit(2) terminate the calling process

       #include <libexplian/fchdir.h>
       void explain_fchdir_or_die(int fildes);
