[drupal-devel] Question on use of theme_pager() and related functions

[Scott Courtney]

Is there a good example somewhere illustrating the correct use of calls to
theme('pager',....)?

I'm trying to use this function, and I've actually got it working except for
one issue: I don't know how to tell it the actual number of rows that were
returned from my database query.

I see the "tags" array that can be passed, and it *looks* as if that would
be the right thing to do. But node.module, statistics.module, and all the
others I can find in Drupal core seem to always pass NULL for that parameter
to theme_pager(). So I'm led to conclude that somehow theme_pager() gets this
information from elsewhere in the "normal" case.

The example modules, as luck would have it, don't use this feature.

Suggestions?

Scott
