50 | * Report the user's preferred locale. |

52 | * This returns an array of SDL_Locale structs, the final item zeroed out. |
53 | * When the caller is done with this array, it should call SDL_free() on the |
54 | * returned value; all the memory involved is allocated in a single block, so |
55 | * a single SDL_free() will suffice. |
56 | * |
57 | * Returned language strings are in the format xx, where 'xx' is an ISO-639 |
58 | * language specifier (such as "en" for English, "de" for German, etc). |
59 | * Country strings are in the format YY, where "YY" is an ISO-3166 country |
60 | * code (such as "US" for the United States, "CA" for Canada, etc). Country |
61 | * might be NULL if there's no specific guidance on them (so you might get { |
62 | * "en", "US" } for American English, but { "en", NULL } means "English |
63 | * language, generically"). Language strings are never NULL, except to |
64 | * terminate the array. |
65 | * |
66 | * Please note that not all of these strings are 2 characters; some are three |
67 | * or more. |
68 | * |
69 | * The returned list of locales are in the order of the user's preference. For |
70 | * example, a German citizen that is fluent in US English and knows enough |
71 | * Japanese to navigate around Tokyo might have a list like: { "de", "en_US", |
72 | * "jp", NULL }. Someone from England might prefer British English (where |
73 | * "color" is spelled "colour", etc), but will settle for anything like it: { |
74 | * "en_GB", "en", NULL }. |
75 | * |
76 | * This function returns NULL on error, including when the platform does not |
77 | * supply this information at all. |
78 | * |
79 | * This might be a "slow" call that has to query the operating system. It's |
80 | * best to ask for this once and save the results. However, this list can |
81 | * change, usually because the user has changed a system preference outside of |
82 | * your program; SDL will send an SDL_LOCALECHANGED event in this case, if |
83 | * possible, and you can call this function again to get an updated copy of |
84 | * preferred locales. |
85 | * |
86 | * \return array of locales, terminated with a locale with a NULL language |
87 | * field. Will return NULL on error. |

89 | * \since This function is available since SDL 2.0.14. |
