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.

Managing memory for strings and characters

You must make buffers large enough to hold text in any of the languages that your application will handle.

If your application will handle many languages, you must ensure that allocated buffers are large enough to hold translated versions of the text. If your application will handle Asian (multibyte) languages, you need to replace single-byte buffers with multibyte- or wide-character buffers.

Important: Any memory that functions allocate remains allocated only for the duration of the function. It does not remain after the function returns. Therefore, you must manage memory for multibyte-character and wide-character strings.
