From 0f6ef690b3118882121ed67561c7ce2660cfebe1 Mon Sep 17 00:00:00 2001 From: theraven Date: Sun, 20 Nov 2011 14:45:42 +0000 Subject: Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a load of _l suffixed versions of various standard library functions that use the global locale, making them take an explicit locale parameter. Also adds support for per-thread locales. This work was funded by the FreeBSD Foundation. Please test any code you have that uses the C standard locale functions!
