                                                                                       explain_utimens_or_die(3)

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

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

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

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

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

       explain_utimens_or_die - change file timestamps and report errors

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

       The explain_utimens_on_error function always returns the value return by the  wrapped  utimens(2)  system
       call.

utimens(2)
               change file last access and modification times

       explain_utimens(3)
               explain utimens(2) errors

       exit(2) terminate the calling process

       #include <libexplain/utimens.h>
       void explain_utimens_or_die(const char *pathname, const struct timespec *data);
       int explain_utimens_on_error(const char *pathname, const struct timespec *data);
