Returning an error instead of simply calling die allows more robust error handling. Secondly initialisation may continue even if the messages have not been loaded which is more friendly than simply dropping dead with no communication to the user.

/** \file
|
|
* Localised message support (interface).
|
|
*
|
|
* The messages module loads a file of keys and associated strings, and
|
|
* provides fast lookup by key. The messages file consists of key:value lines,
|
|
* comment lines starting with #, and other lines are ignored. Use
|
|
* messages_load() to read the file into memory. To lookup a key, use
|
|
* messages_get("key").
|
|
*
|
|
* It can also load additional messages files into different contexts and allow
|
|
* you to look up values in it independantly from the standard shared Messages
|
|
* file table. Use the _ctx versions of the functions to do this.
