/* _gtk_get_lc_ctype:
 *
 * Return the Unix-style locale string for the language currently in
 * effect. On Unix systems, this is the return value from
74
 * `setlocale(LC_CTYPE, NULL)`, and the user can
75 76 77 78 79 80 81
 * affect this through the environment variables LC_ALL, LC_CTYPE or
 * LANG (checked in that order). The locale strings typically is in
 * the form lang_COUNTRY, where lang is an ISO-639 language code, and
 * COUNTRY is an ISO-3166 country code. For instance, sv_FI for
 * Swedish as written in Finland or pt_BR for Portuguese as written in
 * Brazil.
 *
82 83
 * On Windows, the C library doesn’t use any such environment
 * variables, and setting them won’t affect the behaviour of functions
84 85 86 87 88 89
 * like ctime(). The user sets the locale through the Regional Options
 * in the Control Panel. The C library (in the setlocale() function)
 * does not use country and language codes, but country and language
 * names spelled out in English.
 * However, this function does check the above environment
 * variables, and does return a Unix-style locale string based on
90
 * either said environment variables or the thread’s current locale.
91
 *
92
 * Returns: a dynamically allocated string, free with g_free().
