Description

Usage

pangoLanguageGetDefault()

Details

On Unix systems, this is the return value is derived from setlocale(LC_CTYPE, NULL), and the user can affect this through the environment variables LC_ALL, LC_CTYPE or LANG (checked in that order). The locale string 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.

On Windows, the C library does not use any such environment variables, and setting them won't affect the behavior of functions 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 either said environment variables or the thread's current locale.

Your application should call setlocale(LC_ALL, ""); for the user settings to take effect. Gtk+ does this in its initialization functions automatically (by calling gtkSetLocale()). See man setlocale for more details. Since 1.16

Value

[PangoLanguage] the default language as a PangoLanguage, must not be freed.
