It seems as though it is simply not implemented, I found a variety of links that all support this: https://stackoverflow.com/a/40162721 https://stackoverflow.com/questions/38322363/when-will-the-safe-string-functions-of-c11-be-part-of-glibc https://gcc.gnu.org/wiki/C11Status (which states that Annex K is not implemented) http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1967.htm HTH -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup
