* Report the user's preferred locale.

|
|
* This returns an array of SDL_Locale structs, the final item zeroed out.
|
|
* When the caller is done with this array, it should call SDL_free() on the
|
|
* returned value; all the memory involved is allocated in a single block, so
|
|
* a single SDL_free() will suffice.
|
|
*
|
|
* Returned language strings are in the format xx, where 'xx' is an ISO-639
|
|
* language specifier (such as "en" for English, "de" for German, etc).
|
|
* Country strings are in the format YY, where "YY" is an ISO-3166 country
|
|
* code (such as "US" for the United States, "CA" for Canada, etc). Country
|
|
* might be NULL if there's no specific guidance on them (so you might get {
|
|
* "en", "US" } for American English, but { "en", NULL } means "English
|
|
* language, generically"). Language strings are never NULL, except to
|
|
* terminate the array.
|
|
*
|
|
* Please note that not all of these strings are 2 characters; some are three
|
|
* or more.
|
|
*
|
|
* The returned list of locales are in the order of the user's preference. For
|
|
* example, a German citizen that is fluent in US English and knows enough
|
|
* Japanese to navigate around Tokyo might have a list like: { "de", "en_US",
|
|
* "jp", NULL }. Someone from England might prefer British English (where
|
|
* "color" is spelled "colour", etc), but will settle for anything like it: {
|
|
* "en_GB", "en", NULL }.
|
|
*
|
|
* This function returns NULL on error, including when the platform does not
|
|
* supply this information at all.
|
|
*
|
|
* This might be a "slow" call that has to query the operating system. It's
|
|
* best to ask for this once and save the results. However, this list can
|
|
* change, usually because the user has changed a system preference outside of
|
|
* your program; SDL will send an SDL_LOCALECHANGED event in this case, if
|
|
* possible, and you can call this function again to get an updated copy of
|
|
* preferred locales.
|
|
*
|
|
* \return array of locales, terminated with a locale with a NULL language
|
|
* field. Will return NULL on error.
|
|
*
|
|
* \since This function is available since SDL 2.0.14.
