                                                                                     explain_utimensat_or_die(3)

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

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

       fildes  The fildes, exactly as to be passed to the utimensat(2) system call.

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

       data    The data, exactly as to be passed to the utimensat(2) system call.

       flags   The flags, exactly as to be passed to the utimensat(2) system call.

       The explain_utimensat_or_die function is intended to be used  in  a  fashion  similar  to  the  following
       example:
              explain_utimensat_or_die(fildes, pathname, data, flags);

       explain_utimensat_or_die - change file timestamps and report errors

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

       The  explain_utimensat_on_error  function  always  returns  the  value return by the wrapped utimensat(2)
       system call.

utimensat(2)
               change file timestamps with nanosecond precision

       explain_utimensat(3)
               explain utimensat(2) errors

       exit(2) terminate the calling process
