POSIX.1-2024 adds getlocalename_l(), which returns the name of the locale of one category of a locale object. NuttX supports only the "C" locale, so the function returns "C" for every valid category, and NULL with errno set to EINVAL for an invalid one. It is built with CONFIG_LIBC_LOCALE, like the other locale functions. Assisted-by: Claude Code:claude-opus-5-5 Signed-off-by: Marco Casaroli <marco.casaroli@gmail.com>
