Description
The internationalization package provides a convenient method of writ‐
ing or converting applications so that they can operate in the applica‐
tion user's natural language.
The package consists of the following:
· Tools for the creation and modification of message catalogs
· An international function library, which is called libi
· A set of international functions available in the C library,
libc
· An international compiler that creates language support data‐
bases from special source files
· An announcement and initialization mechanism
· A utility for converting data from one codeset to another code‐
set
When you use international library functions in a C program, compile it
with the option to include libi, as shown:
% cc -o prog prog.c -li
Some of the international functions are available in the standard C
library. You need not compile with the option if you use only those
functions. The functions that are available in the standard C library
are and

Header Files
i_defs.h contains language support database structure
i_errno.h contains error numbers and messages
langinfo.h contains the langinfo definitions for the
locale database
locale.h contains the declarations used by the ANSI
setlocale and localeconv functions
nl_types.h contains the definitions for all the inter‐
nationalization (libi) functions
