DataBlade API Programmer's Guide

The Informix® DataBlade® API Programmer's Guide describes information about the DataBlade API, the C-language application programming interface (API) provided with HCL Informix.

You can use the DataBlade API to develop client LIBMI applications and C user-defined routines (UDRs) that access data in the HCL Informix database.

These topics explain how to use the DataBlade API functions. The companion publication, the Informix DataBlade API Function Reference, describes the functions in alphabetical order.

These topics are written for the following users:
  • Database-application programmers
  • DataBlade developers
  • Developers of C UDRs
To understand these topics, you need to have the following background:
  • A working knowledge of your computer, your operating system, and the utilities that your operating system provides
  • Some experience working with relational databases or exposure to database concepts
  • Some experience with computer programming in the C programming language
  • Some experience with database design and the optimization of database queries
These topics use the following conventions to specify DataBlade API function syntax:
  • Brackets ( [ ] ) surround optional items.
  • Braces( { } ) surround items that can be repeated.
  • A vertical line ( | ) separates alternatives.
  • Function parameters are italicized; arguments that you must specify as shown are not italicized.
