DataBlade® API Function Reference
The Informix® DataBlade® API Function Reference describes the DataBlade® API functions and the subset of Informix® ESQL/C functions that the DataBlade® API supports.
This C-language application programming interface is provided with HCL Informix®. You can use the DataBlade® API to develop client LIBMI applications and C user-defined routines that access data in the HCL Informix® database.
The Informix® DataBlade® API Programmer's Guide, a companion document to the function reference, explains how to use the functions in client LIBMI applications and user-defined routines.
These topics are written for the following users:
- Database-application programmers
- DataBlade® developers

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
