perl function closedir

The closedir function in Perl is used to close a directory handle that was previously opened with opendir. Here's an example of how to use closedir:

# Open a directory handle
my $dir = "/path/to/directory";
opendir my $dh, $dir or die "Can't open $dir: $!";

# Iterate over the directory entries
while (my $entry = readdir $dh) {
    # ... do something with $entry ...
}

# Close the directory handle
closedir $dh;

In this example, the opendir function is used to open a directory handle for the directory located at "/path/to/directory". The while loop is used to iterate over the directory entries using the readdir function.

After all of the directory entries have been processed, the closedir function is called to close the directory handle.

It's important to note that failing to close a directory handle can result in resource leaks and unexpected behavior. Always remember to close directory handles when you're finished using them.
