Client APIs and toolsYou can use the HCL Informix® implementation of client APIs to develop applications for Informix® database servers.
APIThe Informix® GLS API Programmer's Guide describes the global language support (GLS) application programming interface (API) available in Informix® ESQL/C and HCL Informix® DataBlade® modules.
Character processingThese topics describe the character-processing capabilities of the library.
Other operationsIn addition to the operations on characters and strings, the library provides support for terminating characters and strings, allocating memory for characters and strings, and truncating and fragmenting strings.
Managing memory for strings and charactersYou must make buffers large enough to hold text in any of the languages that your application will handle.
String deallocationThe library does not automatically deallocate memory that you dynamically allocate. Once you no longer need the string buffer, you must ensure that you deallocate any memory that your application has dynamically allocated for multibyte-character and wide-character strings.

String deallocation

The library does not automatically deallocate memory that you dynamically allocate. Once you no longer need the string buffer, you must ensure that you deallocate any memory that your application has dynamically allocated for multibyte-character and wide-character strings.

The DataBlade® API does provide some automatic garbage collection for memory that you allocate dynamically. When this memory is deallocated depends on the memory duration with which it was allocated. However, it is good programming practice to handle memory deallocation implicitly whenever possible. For more information about memory management with the DataBlade API, see the Informix® DataBlade API Programmer's Guide.
