namespace o3tl
{ // A drop-in replacement for safe uses of std::sprintf where it is statically known that the // provided buffer is large enough. Compared to a plain use of std::sprintf, using o3tl::sprintf // for one makes it explicit that the call is considered safe and for another avoids deprecation // warnings on platforms like the macOS 13 SDK that mark std::sprintf as deprecated. Many simple // uses of std::sprintf across the code base can be replaced with alternative code using e.g. // OString::number. This is for the remaining formatting-rich cases for which there is no easy // replacement yet in our C++17 baseline. Ultimately, it should be removed again once alternatives // for those remaining cases, like C++20 std::format, are available. template <std::size_t N, typename... T> int sprintf(char (&s)[N], charconst* format, T&&... arguments)
{ autoconst n = std::snprintf(s, N, format, std::forward<T>(arguments)...);
assert(n < 0 || o3tl::make_unsigned(n) < N);
