explain_utimens_or_die(3)  Library Functions Manual  explain_utimens_or_die(3)

NAME
       explain_utimens_or_die -	change file timestamps and report errors

SYNOPSIS
       #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	 time-
       spec *data);

DESCRIPTION
       The explain_utimens_or_die function is used to call the utimens(2) sys-
       tem 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, ob-
       tained 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.

RETURN VALUE
       The  explain_utimens_or_die  function only returns on success, see uti-
       mens(2) for more	information. On	failure, prints	an explanation and ex-
       its, it does not	return.

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

EXAMPLE
       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);
