@brief Return the language names written in the specified language.
The mlanguage_name_list () function returns a plist of LANGUAGE's
- names written in TARGET language.
+ names written in TARGET language. SCRIPT and TERRITORY, if not #Mnil,
+ specifies which script and territory to concern at first.
LANGUAGE and TARGET must be a symbol whose name is an ISO639-2
3-letter language code or an ISO639-1 2-letter language codes.
TARGET may be #Mnil, in which case, the language of the current
locale is used. If locale is not set or is C, English is used.
+ SCRIPT and TERRITORY must be a symbol whose name is a script and
+ territory name of a locale (e.g. "TW", "SG") respectively.
+
@return
- If the information is available, this function returns a non-empty
- plist whose keys are #Mtext and values are M-texts of the
- translated language names. Otherwise, @c NULL is returned.
+ If the translation is available, this function returns a non-empty
+ plist. The first element has key #MText and the value is an
+ M-text of a translated language name. If the succeeding elements
+ also have key #MText, their values are M-texts of alternate
+ translations.
+
+ If no translation is available, @c NULL is returned.
+
The returned plist should not be modified nor freed.
