NAME

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

SYNOPSIS

       #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);

DESCRIPTION

       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.

RETURN VALUE

       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.

EXAMPLE

       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);
