How To Passing Variable Into Cclipwidget

I’m using these codes in views:

<?php $this->beginClip('someClip'); ?>

    blah, blah, blah

<?php $this->endClip(); ?>

This clip will be rendered in a foreach loop.

I need to passing some dynamic variable into this clip for using CHtml::link to create a dynamci URL.

I search the class references, but there’s seems no argument for the variable.

Does anyone know how to do this?

Thanks a lot.
