Multicultural support sample program

This section contains a sample program fragment, my_example.c, which illustrates globalization through code set independent programming.

Message source file for my_example
A sample message source file for the my_example utility is given here. Note that we defined only one set and three messages in this catalog for illustration purposes only. A typical catalog contains several such messages.
Creation of message header file for my_example
Single-source, single-path code set independent version
The term single-source single-path refers to one path in a single application to be used to process both single-byte and multibyte code sets. The single source single path method eliminates all ifdefs for globalization. All characters are handled the same way, whether they are members of single-byte or multibyte code sets.
Single-source, dual-path version optimized for single-byte code sets
The term single-source dual-path refers to two paths in a single application where one of the paths is chosen at run time depending on the current locale setting, which indicates whether the code set in use is single-byte or multibyte.
