NAME
DirHandle - (obsolete) supply object methods for directory handles
SYNOPSIS
my $d, .) { while (readdir $d) { something($_); } rewind $d; while (readdir $d) { something_else($_); } } # how you would use this module if you were going to use DirHandle; if (my $d = DirHandle->new(“.”)) { while (defined($_ = $d->read)) { something($_); } $d->rewind; while (defined($_ = $d->read)) { something_else($_); } }
DESCRIPTION
There is no reason to use this module nowadays.
The DirHandle
method provide an alternative interface to the
opendir(), closedir(), readdir(), and rewinddir() functions.
Up to Perl 5.5, opendir() could not autovivify a directory handle from
undef
, so using a lexical handle required using a function from Symbol
to create an anonymous glob, which took a separate step. DirHandle
encapsulates this, which allowed cleaner code than opendir(). Since
Perl 5.6, opendir() alone has been all you need for lexical handles.
