// Return a human readable modifier for the version string, e.g. // the channel (dev, beta, stable). Returns true if this operation succeeded, // on success, channel contains one of "", "unknown", "dev" or "beta" (unless // it is a multi-install product, in which case it will return "m", // "unknown-m", "dev-m", or "beta-m"). static bool GetChromeChannelAndModifiers(bool system_install, std::wstring* channel); multi-install會多標上-m 其實就只是個記號 誤判也不理也沒關係
