how to add filter 'tc_show_single_post_content'

Hi..

I want to make add filter of this hooks :

function tc_single_post_display_controller() {
        //check conditional tags : we want to show single post or single custom post types
        global $post;
        $tc_show_single_post_content = isset($post)
        && 'page' != $post -> post_type
        && 'attachment' != $post -> post_type
        && is_singular()
        && !tc__f( '__is_home_empty');
        return apply_filters( 'tc_show_single_post_content', $tc_show_single_post_content );
      }

by simple added / inserted :
&& 'hotel' != $post -> post_type

still confused modifying filter hooks.

Thanks.
