BuddyPress.org

Hello,
I just installed custom fields plugin for buddypress. To use it in my theme it says:
To use in your theme, you can use next functions:

get_fieldmeta( $post_id = null, $name = null, $alone = true) : for post_type
get_fieldmeta_taxo( $term_id = null, $taxonomy = null, $name = null, $alone = true ) : for taxonomy

I am quite new to buddypress, can someone explain how to use the above called functions and implement them in my theme?

Thanks a lot.
