                                                                                      explain_pathconf_or_die(3)

       The  explain_pathconf_or_die  function  is  used  to  call  the  pathconf(3)  system call.  On failure an
       explanation will be printed to stderr, obtained from explain_pathconf(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:
              long value = explain_pathconf_or_die(pathname, name);
       Note that a −1 return value is still possible, meaning the system does not have a limit for the requested
       resource.

       pathname
               The pathname, exactly as to be passed to the pathconf(3) system call.

       name    The name, exactly as to be passed to the pathconf(3) system call.

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