perl function telldir

The telldir function in Perl returns the current position of the directory read pointer for a directory opened by opendir.

Here's an example:

opendir(DIR, "/usr/bin") or die "Cannot open directory: $!";
while (my $file = readdir(DIR)) {
    print "$file\n";
}
closedir(DIR);

# Get the current position of the directory read pointer
my $pos = telldir(DIR);
print "Current position: $pos\n";

In this example, the opendir function opens the directory /usr/bin and the readdir function reads the contents of the directory one by one. After reading all the directory entries, the closedir function closes the directory.

Finally, the telldir function is used to get the current position of the directory read pointer. The current position is printed to the console. Note that in this example, the telldir function is called after the directory has been closed, which is not meaningful. In practice, the telldir function should be called while the directory is still open.
