How two place this php variable inside this function's "();"
Sotty I don't know how it that called. It is the function's `();`

For instance,

This is how you place the variable `$topic_id` inside the parenteses:

    <?php bbp_topic_permalink( $topic_id ); ?>
    
    <?php bbp_topic_title( $topic_id ); ?>">
    
    <?php bbp_topic_reply_count( $topic_id ); ?>

Now, I need to do the same with a function called `bbp_get_topic_author_link`: 

    <span><?php printf( __( 'Started by: %1$s', 'bbpress' ), bbp_get_topic_author_link( array( 'size' => '14' ) ) ); ?></span>

But I have no idea how.

Any suggestions?
