A struct to provide locale data.
Defined in <SDL3/SDL_locale.h>
typedef struct SDL_Locale
{
const char *language; /**< A language name, like "en" for English. */
const char *country; /**< A country, like "US" for America. Can be NULL. */
} SDL_Locale;Locale data is split into a spoken language, like English, and an optional country, like Canada.
Language strings are ISO-639 language specifiers (such as "en" for English, "de" for German, etc). Country strings are ISO-3166 country codes (such as "US" for the United States, "CA" for Canada, etc). The country might be NULL if there's no specific guidance on them (so you might have { "en", "US" } for American English, but { "en", NULL } means "English language, generically"). Language strings are never NULL.
Please note that not all of these strings are 2 characters; some are three or more.
This struct is available since SDL 3.2.0.
