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® Developers KitThe DataBlade® Developers Kit (DBDK) guides contain information about the tools you can use to develop and package DataBlade® modules, which extend the functionality of HCL Informix® databases.
DBDK InfoShelfThe DataBlade® Developers Kit InfoShelf is designed to help you work with BladeSmith.
DataBlade® Developers Kit TutorialThe Tutorial is a set of exercises that demonstrate how to create extensions to HCL Informix® and package them as DataBlade® modules by using DBDK. Support for DataBlade Developers Kit (DBDK) is removed starting Informix Server 14.10.xC6.

Binary send and receive functions

Binary send and receive functions

Binary send and receive internal support functions transfer the binary representation of the opaque data type to and from the client.

The client and server can execute on different platforms, with different representations for some data types. When a client connects with a database server, it sends a description of its data representation. The database server calls the binary send function to convert opaque data type values to the client format before sending them to the client. The binary receive function converts a value arriving from the client binary format to the database server binary format.

BladeSmith generates the complete code for these functions.

See the Informix® DataBlade® Developers Kit User's Guide for more information.
