From d88e5dfa8b989dafff4b748bfb3cba3512c8482e Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sat, 20 Oct 2018 21:54:20 -0400 Subject: adapt setlocale to support possibility of failure introduce a new LOC_MAP_FAILED sentinel for errors, since null pointers for a category's locale map indicate the C locale. at this time, __get_locale does not fail, so there should be no functional change by this commit. --- src/internal/locale_impl.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/internal') diff --git a/src/internal/locale_impl.h b/src/internal/locale_impl.h index 0b5e00cf..741a71c4 100644 --- a/src/internal/locale_impl.h +++ b/src/internal/locale_impl.h @@ -27,6 +27,8 @@ hidden const char *__lctrans_impl(const char *, const struct __locale_map *); hidden int __loc_is_allocated(locale_t); hidden char *__gettextdomain(void); +#define LOC_MAP_FAILED ((const struct __locale_map *)-1) + #define LCTRANS(msg, lc, loc) __lctrans(msg, (loc)->cat[(lc)]) #define LCTRANS_CUR(msg) __lctrans_cur(msg) -- cgit v1.2.1
