                                                                                       explain_fstatat_or_die(3)

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

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

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

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

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

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

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

       explain_fstatat_or_die - get file status relative to a dir fd and report errors

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

       The explain_fstatat_on_error function always returns the value return by the  wrapped  fstatat(2)  system
       call.

fstatat(2)
               get file status relative to a directory file descriptor

       explain_fstatat(3)
               explain fstatat(2) errors

       exit(2) terminate the calling process

       #include <libexplain/fstatat.h>
       void explain_fstatat_or_die(int fildes, const char *pathname, struct stat *data, int flags);
       int explain_fstatat_on_error(int fildes, const char *pathname, struct stat *data, int flags);
