How to read Linux File attributes?

Another question is: How to read the attributes of a Linux file or Linux directory from BlackBox?
Is there a call available via the Lin library? Where can I find a description or an explanation about the Lin library?

I got some copypaste from HostFiles. Information about libc library you can find in the Internet documentation for Linux.

Code: Select all
   IMPORT  Log, Libc := LinLibc, HostFiles, Strings;
      ShortName = ARRAY 260 * 4 OF SHORTCHAR;
      read = 8;
      write = 7;
      execute = 6;
      file = 15;
      VAR s: ShortName; ok1, res: INTEGER; buf: Libc.stat_t;
      Strings.StringToUtf8('/home/dia/blackbox/test', s, ok1);
      res := Libc.__xstat(Libc._STAT_VER_LINUX, s, buf); (* macro expansion of "stat" *)
      Log.String("is directory "); Log.Bool(~ (file IN buf.st_mode)); Log.Ln;
      Log.String("all bits "); Log.Set(buf.st_mode); Log.Ln;
   END Stat;

END DemoRun.
