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);
