 This is because the cd9660 file system doesn't implement d_type.

man dirent or man readdir didn`t note that it`s possible to have this
behavior.

#define _POSIX_SOURCE

#include sys/types.h
#include dirent.h
...
  while((dent_p = readdir(dir_p)))
  {
printf(%-40s (type: %s)\n, dent_p-d_name, types[dent_p-d_type]);
  }
 
 This probably shouldn't compile, since d_type isn't in POSIX.1.  POSIX.1

It compiles, output above.

 only guarantees d_name in struct dirent.  Names beginning with d_ are
 reserved for use in dirent.h, but FreeBSD normally attempts to give
 strict POSIX.1 if _POSIX_SOURCE is defined.

So it`s a bug, but in a different way I want. :(

Without _POSIX_SOURCE it didn`t work either.
Is it useless, because we can only say it works _perhaps_ (and we
have to stat the entry), or is it a bug?

Bye,
Alexander.

Hi,

attached is the source of a test program.

With the CD of my ISDN card it produces:

Every other CD I tried shows similar results. With ufs or msdos it
displays the correct type (dir, reg, ...).

FreeBSD 4.0-CURRENT #0: Thu Jan 21

ls works because it stats the file.

#define _POSIX_SOURCE

#include dirent.h
...
  while((dent_p = readdir(dir_p)))
  {
printf(%-40s (type: %s)\n, dent_p-d_name, types[dent_p-d_type]);
