From the User Guide:

form_open_multipart()

This function is absolutely identical to the form_open() tag above except that it adds a multipart attribute, which is necessary if you would like to use the form to upload files with.

So, you would use it in the same way you use form_open(). Example:

form_open_multipart('controller', 'id="my_id"');

Or:

form_open_multipart('controller', array('id' => 'my_id'));
