[Mediawiki-l] How can i paginate database query?

[VicHaunter]

Hello,
I'm creating a extension that show a list of articles included in two categories.
The problem is that some ones have a lot of results and i can't paginate with ordynary methods because the wiki dont get my vars across the urls bar.

Someone knows how i can paginate a mysql query like the pagination in the Categories in mediawiki with a extension?
Thankyou
