working with stored procedures

Hi ,
I am trying to create a stored procedure that returns a user defined type. The following piece of code shows the way I am trying to do it.
regy1=> create function regyuser_rec(int) returns varchar as ' declare
regy1'> v_userid alias for $1;
regy1'> output_rec varchar(400);
regy1'> user_rec record;
regy1'>
regy1'> begin
regy1'>
regy1'> select fname ,lname into user_rec from regyuser
regy1'> where userid = v_userid;
regy1'> output_rec := user_rec;
regy1'> return output_rec;
regy1'> end;
regy1'> ' language 'plpgsql';
CREATE
regy1=> select regyuser_rec(2);
ERROR: Attribute 'user_rec' not found

Does a postgresql function returns a user defined object?
If so, could I have an example.
I am new to postgresql, and was trying to figure out what's wrong with my code.Could some one help me.
Thanks,
Radhika.
