The only objective benefit to using C is that it avoids namespace pollution by creating globs to hold directory handles. =cut require 5.000; use Carp; use Symbol; sub new { @_ >= 1 && @_ <= 2 or croak 'usage: DirHandle->new( [DIRNAME] )'; my $class = shift; my $dh = gensym; if (@_) { DirHandle::open($dh, $_[0]) or return undef; } bless $dh, $class; } sub DESTROY { my ($dh) = @_; # Don't warn about already being closed as it may have been closed # correctly, or maybe never opened at all. local($., $@, $!, $^E, $?); no warnings 'io'; closedir($dh); } sub open { @_ == 2 or croak 'usage: $dh->open(DIRNAME)'; my ($dh, $dirname) = @_; opendir($dh, $dirname); } sub close { @_ == 1 or croak 'usage: $dh->close()'; my ($dh) = @_; closedir($dh); } sub read { @_ == 1 or croak 'usage: $dh->read()'; my ($dh) = @_; readdir($dh); } sub rewind { @_ == 1 or croak 'usage: $dh->rewind()'; my ($dh) = @_; rewinddir($dh); } 1;
