How do you name a function in template.php to get picked up by theme() calls in page.tpl.php?

Question

I have a Drupal 6 site with a simple theme I'm creating called NPT. In page.tpl I have this:

<?php print theme('links', $primary_links, array('class' => 'links primary-links')) ?>

That successfully calls this function in template.php:

npt_links()

However, I also have this in page.tpl.php:

<?php print theme('clinks', $secondary_links, array('class' => 'secondary-links')) ?>

And that does not call this function in template.php:

npt_clinks()

But it should, as I'm calling the "clinks" hook parameter in the theme() call.

Any ideas why this hook isn't being called?

Answer 1

Have you declared the clinks theme function in the theme registry?
