External functions (UDFs)

External functions must be “declared” (made known) to the database before they can be used. Firebird ships with two external function libraries:

  • ib_udf – inherited from InterBase;
  • fbudf – a new library using descriptors, present as from Firebird 1.0 (Windows) and 1.5 (Linux).

Users can also create their own UDF libraries or acquire them from third parties.
