Locale Support For C User-Defined Routines (IDS and DB API)

Dynamic Server allows you to create user-defined routines (UDRs) that are written in the C programming language. These C UDRs use the DataBlade API to communicate with the database server. For a complete description of the DataBlade API, see the IBM Informix: DataBlade API Programmer's Guide. This section describes how to internationalize a C UDR.

Internationalization is the process of creating a user-defined routine (UDR) that can support different languages, territories, and code sets without changing or recompiling its code.

An internationalized C UDR must handle the following GLS considerations:

• Where can the UDR use non-ASCII characters in source code?
• What steps must the C UDR take when copying character data?
• How can the UDR access GLS locales?
• How does the UDR handle code-set conversion?
• How does the UDR handle locale-specific end-user formats?
• How can the UDR access internationalized exception messages?
• How can the UDR access internationalized tracing messages?
• How do opaque-type support functions handle locale-sensitive data?
