Wordpress Base Path Hook?

Question

What's the wordpress / php hook to link to the base path of the wordpress installation? I want to be able to link to the home page of the wordpress blog, regardless of which directory the theme is installed in.

Answer 1

echo '<a href="' . get_settings('siteurl') . '/wp-admin/index.php">admin</a>';

would give you (as an example)

<a href="http://me.com/blog/wp-admin/index.php">admin</a>

and

<a href="<?php bloginfo('url'); ?>">

would give you

<a href="http://me.com/blog/index.php">
