Extending Informix®Beyond standard relational database objects, HCL Informix® can be extended to handle specialized data types, access methods, routines, and other objects. Informix® includes many built-in extensions that are fully integrated in the database server. Informix® also provides DataBlade® modules, which are packages of extended database objects for a particular purpose and that are installed separately from the database server. Alternatively, you can create your own user-defined objects for Informix®.
Creating extensionsYou can create user-defined data types, routines, access methods, and other database objects to suit your needs. You can use application programming interfaces to write user-defined routines and applications that access data in Informix® databases.
DataBlade® API Programmer's GuideThe Informix® DataBlade® API Programmer's Guide describes information about the DataBlade® API, the C-language application programming interface (API) provided with HCL Informix®.
Data manipulation
Complex data typesThis section describes the complex data types and the functions that the DataBlade® API supports to process collection and row-type data.
Row typesA row type is a complex data type that is made up of a sequence of one or more elements called fields. Each field has a name and a data type. A row type is similar to a C struct data type. The DataBlade® API provides support for row types in both their text and binary representations.
Releasing row resourcesWhen your DataBlade® API module no longer needs the row type (or row) that you allocated, you need to assess whether you can release resources that the row is using, specifically the row descriptor and the row structure.

Releasing row resources

When your DataBlade® API module no longer needs the row type (or row) that you allocated, you need to assess whether you can release resources that the row is using, specifically the row descriptor and the row structure.
