| <h3 class="section">8.1 X/Open Message Catalog Handling</h3> |
| |
| <p>The <code>catgets</code> functions are based on the simple scheme: |
| |
| <blockquote> |
| Associate every message to translate in the source code with a unique |
| identifier. To retrieve a message from a catalog file solely the |
| identifier is used. |
| </blockquote> |
| |
| <p>This means for the author of the program that s/he will have to make |
| sure the meaning of the identifier in the program code and in the |
| message catalogs are always the same. |
| |
| <p>Before a message can be translated the catalog file must be located. |
| The user of the program must be able to guide the responsible function |
| to find whatever catalog the user wants. This is separated from what |
| the programmer had in mind. |
| |
| <p>All the types, constants and functions for the <code>catgets</code> functions |
| are defined/declared in the <samp><span class="file">nl_types.h</span></samp> header file. |
