Installing UDFs in MySQL:
-------------------------

      DROP FUNCTION IF EXISTS epglv;
      DROP FUNCTION IF EXISTS epglvr;
      CREATE FUNCTION epglv RETURNS INT SONAME 'mysqlepglv.so';
      CREATE FUNCTION epglvr RETURNS INT SONAME 'mysqlepglv.so';

      mysql> SELECT * FROM mysql.func;
      +-----------+-----+-------------------+----------+
      | name      | ret | dl                | type     |
      +-----------+-----+-------------------+----------+
      | epglv     |   2 | mysqlepglv.so     | function |

    Before changing the lib in MySQLs plugin dir DROP the function if it already exist.
    Otherwise you can get mysql in a undefined state and a mysql reinstall may necessary!
