The Message Facility consists of
standard defined subroutines and commands, and manufacturer value-added
extensions to support externalized message catalogs. These catalogs are
used by an application to retrieve and display messages, as needed. The
following Message Facility subroutines get messages for an application:
| catopen | Opens a catalog. |
| catgets | Gets a messages from a catalog. |
| catclose | Closes a catalog. |
| strerror | Maps an error number to an error-message string appropriate for the current locale. |
