NAME

       explain_futimens_or_die - change file timestamps and report errors

SYNOPSIS

       #include <libexplain/futimens.h>
       void explain_futimens_or_die(int fildes, const struct time_spec *data);
       int explain_futimens_on_error(int fildes, const struct time_spec *data);

DESCRIPTION

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

       The  explain_futimens_on_error  function  is  used  to  call  the  futimens(3) system call. On failure an
       explanation will be printed to stderr, obtained from the explain_futimens(3) function, but still  returns
       to the caller.

       fildes  The fildes, exactly as to be passed to the futimens(3) system call.

       data    The data, exactly as to be passed to the futimens(3) system call.

RETURN VALUE

       The  explain_futimens_or_die  function  only returns on success, see futimens(3) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_futimens_on_error function always returns the value return by the wrapped futimens(3)  system
       call.

EXAMPLE

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