Hello Monks,

I am writing a program that needs to open directories with the O_NOFOLLOW flag. Since opendir() does not support that, I use sysopen(): 

  sysopen my $dirh, $pathname, O_RDONLY|O_DIRECTORY|O_NOFOLLOW;
Unfortunately, readdir() does not accept the handle from sysopen: 
  readdir $dirh;

readdir() attempted on invalid dirhandle $dirh
Is there a way to "convert" the handle from sysopen to one accepted by readdir? I have a work-around with chdir() but that's pretty ugly (error handling not included here): 
  my $cwd = getcwd();
  sysopen my $dirh, $pathname, O_RDONLY|O_DIRECTORY|O_NOFOLLOW;
  chdir $dirh;
  opendir my $dirh2, '.';
  my @files = readdir $dirh2;
  closedir $dirh2;
  chdir $cwd;
