You cannot 'fetch' from a pl/sql routine. You can return a CURSOR from pl/sql and fetch from it. You'd be using ofen, ofetch or some routine like that to fetch rows from the CURSOR.
check out cursor variables in the pl/sql manual for more info on those. Check out $ORACLE_HOME/rdbms/demo/oci11.c for an OCI example of fetching from cursor variables returned from pl/sql....
